what is the atomic bomb?
102659
a weapon which derives its destructive force from nuclear reactions of either nuclear fission or the more powerful fusion. As a result, even a nuclear weapon with a relatively small yield is significantly more powerful than the largest conventional explosives, and a single weapon can be capable of destroying or seriously disabling an entire city.

Has to be wikipedia.org\n\nBut if can focus more on the delivery systems. For example, Pershing (land-based) and Trident (submarine-based).\n\nAlso read about chemical and biological agents as bombs, and the hydrogen bomb. Read about both nuclear fusion and fission too. Not forgetting about dirty nukes.

they are big bombs that have at their core the splitting of an atom. v dangerous stuff. A single bomb could likely snuff out NYC.

Lots of fallout.  LOTS.\n\nHere's a fun fact; the accident at Chernobyl plant released 200 times the radiation of both atomic bombs dropped on Japan.  The radiation reached every corner of Europe.  And that was just one reactor out of four.\nSo a bomb dropped on a nuclear plant would probably be the end of everything within 500 miles.

The bombs used in Hiroshima and Nagasaki were fission bombs, with respective yields of 15 and 22 kilotons.  A fission bomb generates about 4,000,000 Megajoules of energy per kiloton of explosive force, so the Hiroshima bomb would have produced 60,000,000 Megajoules of energy while the Nagasaki bomb produced 88,000,000 Megajoules.

A "dirty bomb" is one that spreads radiation through a conventional (chemical) explosion, not a nuclear one.  In a dirty bomb, a conventional explosive and fusing mechanism are surrounded by highly radioactive material of some sort.\nIt is difficult, and requires a very high degree of mechanical/electrical skill, to construct a nuclear explosive device.  A nuclear (fission) bomb uses conventional explosives fired all at the exact same time to bring together units of fissile material (usually uranium-235 or some isotope of plutonium; there are others), resulting in a "critical mass," or more correctly "prompt criticality" which results in the almost instantaneous release of large amounts of energy.  Fusion bombs (commonly known as H-bombs) use a fission reaction to create the high temperature necessary to start a fusion chain reaction.\nSo, basically, the difference between a "dirty bomb" and a true nuclear bomb is the reaction that creates the explosion.

A nuclear weapon is a weapon which derives its destructive force from nuclear reactions of fission or fusion. As a result, even a nuclear weapon with a relatively small yield is significantly more powerful than the largest conventional explosives, and a single weapon is capable of destroying an entire city.\n\nIn the history of warfare, nuclear weapons have been used only twice, both during the closing days of World War II. The first event occurred on the morning of August 6, 1945, when the United States dropped a uranium gun-type device code-named "Little Boy" on the Japanese city of Hiroshima. The second event occurred three days later when a plutonium implosion-type device code-named "Fat Man" was dropped on the city of Nagasaki. The use of these weapons, which resulted in the immediate deaths of around 100,000 to 200,000 individuals and even more over time, was and remains controversial — critics around the world charged that they were unnecessary acts of mass killing, while others claimed that they ultimately reduced casualties on both sides by hastening the end of the war. This topic has seen increased debate recently in the wake of increased terrorism involving killings of civilians by both state and non-state players, with parties claiming that the end justifies the means (see Atomic bombings of Hiroshima and Nagasaki for a full discussion).\n\nSince the Hiroshima and Nagasaki bombings, nuclear weapons have been detonated on over two thousand occasions for testing and demonstration purposes. The only countries known to have detonated such weapons are (chronologically) the United States, Soviet Union, United Kingdom, France, People's Republic of China, India, Pakistan, and North Korea. Various other countries may hold nuclear weapons but have never publicly admitted possession, or their claims to possession have not been verified. For example, Israel has modern airborne delivery systems and appears to have an extensive nuclear program with hundreds of warheads (see Israel and weapons of mass destruction), though it officially maintains a policy of "ambiguity" with respect to its actual possession of nuclear weapons. Iran currently stands accused by a number of governments of attempting to develop nuclear capabilities, though its government claims that its acknowledged nuclear activities, such as uranium enrichment, are for peaceful purposes. South Africa also secretly developed a small nuclear arsenal, but disassembled it in the early 1990s. (For more information see List of countries with nuclear weapons.)\n\nApart from their use as weapons, nuclear explosives have been tested and used for various non-military uses.

An electromagnetic bomb or E-bomb is a weapon designed to disable electronics on a wide scale with an electromagnetic pulse. The electromagnetic pulse was first observed during high altitude nuclear weapon detonations. An electromatic pulse lasts for less than a nanosecond, and travels outward in every direction as an electromagnetic shock wave.This shock wave will induce heavy currents in all electronic gadgets that mainly contain semiconducting and conducting materials.This produces immense heat that simply fries the circuitry inside and destroys them. As such, while not being directly responsible for the loss of lives, these weapons are capable of disabling electronic systems on which industrialized nations are highly dependent.\n\nElectromagnetic weapons are still mostly classified and research surrounding them is highly secretive. It is generally thought that E-bombs use explosively pumped flux compression generator technology as their power source.

During WW2, there was a top secret project using the best minds of the world except for Einstein and a few others as they opposed the project called Manhattan Project.  Its goal was to harness the power of the atom and turn it into a weapon.  They did and the first bomb was fired in the Nevada dessert and was called the Trinity test.\n\nThe bomb was then tasked to be weaponsized and a B29 was specially fitted and modified to carey the giant beast of a bomb.  While the bomb was being constructed and designed and such, the military command along with the president were debating the outcomes of a land invasion of Japan.  After much delberation of whther the bomb should be used or hundereds of thousnads of troops be used in a invasion, it was decided to drop the Uranium based bomb on a designated city that had not suffered the same bombing campaign as the other cities had.  The first choice (the name of the city escapes me) was covered with clouds so the secondary target of Hiroshima was chosen and bombed.  The Japanese were stunned at the new weapon.  Emperor Hirohito wanted to surrender to the Americans but the Military did not want to lose face by surrendering.  in the turmoil of the that followed with the debates of surrender or not, Nagasaki was wiped away by a Plutonium based weapon.\n\nAt that time the Emperor won the fight and surrendered to the Americans.  They also did this to avoid retribution by the Russians whom they have faught for many years with prior.\n\nAfter the war was over, a tour was done by the American command and found out that they would have had overwhelming casualties had they attempted to land on Japan as they had 3 lines fo trenches, bunkers, and other assorted fortifications armed with soldiers and civillians.\n\nI hope this answered your question!

Tsar Bomba (Russian: Царь-бомба, literally "Tsar-bomb") is the Western name for the largest, most powerful nuclear weapon ever detonated or built. Developed by the Soviet Union, the bomb of about 50 megatons was codenamed Ivan by its developers.\n\nThe bomb was tested on October 30, 1961 in Novaya Zemlya, an island in the Arctic Sea. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout...\n\nCodenamed "Ivan" during its development, the Tsar Bomba was not intended for use in warfare, but should be seen as an instance of the Cold War-era saber-rattling indulged in by the USSR and the USA.\n\nThe Tsar Bomba was a multi-stage hydrogen bomb with a yield of about 50 megatons (Mt). The initial three-stage (fission-fusion-fission) design was capable of approximately 100 Mt, but at a cost of too much radioactive fallout. To limit fallout, the third stage, consisting of a uranium-238 fission tamper (which greatly amplifies the reaction by fissioning uranium atoms with fast neutrons from the fusion reaction), was replaced with one made of lead. This eliminated fast fission by the fusion-stage neutrons, so that approximately 97% of the total energy resulted from the fusion stage alone (as such, it was one of the "cleanest" nuclear bombs ever created, generating a very low amount of fallout relative to its yield). There was a strong incentive for this feature regression, as most of the fallout from a test of the bomb would fall on populated Soviet territory.\n\nThe bomb, weighing 27 tonnes, was so large (8 meters long by 2 m in diameter) that the Tu-95 had to have its bomb bay doors and wing fuel tanks removed. The bomb was attached to an 800 kg fall retardation parachute, which gave the release and observer planes time to fly about 45 km from ground zero. Failing such retardation, the bomb would have either reached its planned detonation altitude so fast it would have turned the test into a suicide mission, or crashed into the ground at high speed, with unpredictable results.\n\nThe Tsar Bomba detonated at 11:32 a.m., located approximately at 73.85° N 54.50° E [2], over the Mityushikha Bay nuclear testing range (Sukhoy Nos Zone C), north of the Arctic Circle on Novaya Zemlya Island in the Arctic Sea. The bomb was dropped from an altitude of 10,500 m, and designed to detonate at a height of 4,000 m over the land surface (4,200 m over sea level) by barometric sensors.\n\nThe original USA estimate of the yield was 57 Mt, but since 1991 all Russian sources have stated its yield as "only" 50 Mt. Nonetheless, Khrushchev warned in a filmed speech to the Communist parliament of the existence of a 100 Mt bomb (technically the design was capable of this yield). The fireball touched the ground, reached nearly as high as the altitude of the release plane, and was seen 1,000 km away. The heat could have caused third degree burns at a distance of 100 km. The subsequent mushroom cloud was about 60 km high and 30–40 km wide. The explosion could be seen and felt in Finland, even breaking windows there.[citation needed] Atmospheric focusing caused blast damage up to 1,000 km away. The seismic shock created by the detonation was measurable even on its third passage around the earth.\n\nSince 50 Mt is 2.1×1017 joules, the average power produced during the entire fission-fusion process, lasting around 3.9×10-8 seconds or 39 nanoseconds, was a power of about 5.3×1024 watts or 5.3 yottawatts. This is equivalent to approximately 1% of the power output of the Sun. The detonation of Tsar Bomba therefore qualifies, even to this day, as being the single most powerful device ever utilized throughout the history of humanity. By contrast, the largest weapon ever produced by the United States, the now-decommissioned B41, had a predicted maximum yield of 25 Mt, and the largest nuclear device ever tested by the USA (Castle Bravo) yielded 15 Mt...\n\n...amazing!\n

A hydrogen bomb is a fusion bomb.\n\nThe uranium / plutonium bombs are fission bombs.\n\nBoth may properly be called atomic or nuclear bombs.\n\nThere are also combinations such as the fisson-fusion-fission bomb which combines features of both types.

nuclear bombs is the general term for any bomb that involves a nuclear reaction, but often is meant to denote a fission bomb that uses uranium or plutonium, like the ones dropped on japan. a hydrogen bomb uses nuclear fusion, which is more powerful, but requires a fission reaction to start it, so a hydrogen bomb contains a fission bomb and hydrogen to undergo fusion\nhydrogen bombs are definitely not more environmentally correct; they cause much more destruction and as much if not more radiatioactivity. this is especially true if they have a uranium "jacket" that creates a second fission explosion after the first fission and fusion.

Any nuclear bomb will create an electromagnetic pulse.  The size of the pulse radius will be approximately related to the blast radius.
