how do they split atoms?
607558
Well, there are two ways. One way is nuclear fission, like in an atomic bomb. A slow-moving neutron is fired into a large atom (like Uranium-235, or Plutonium-239). The neutron hits the atom, causing it to reverberate and stretch, until it splits into two smaller atoms, releasing tons of energy.\n\nThe other way is the way they do it in the lab, using a linear accelerator or a cyclotron. Regardless of the method, a small particle is propelled using powerful magnets to almost the speed of light. It then smashes into a large atom, where it disintegrates into a slurry of subatomic particles.

Atoms do have empty spaces but these spaces are according to their size not ours let me elobrate first that we are not composed of atoms we are composed of cells if any one says atoms then tell that person that atoms are non living whereas cells are living some part of our body are dead cells like nails hairs dead skin at the knuckles etc but the rest is all living cells.\n\n\nThings don't fall through other things because they are levitating on an electrostatic field! I am not kidding! When you sit on a chair, you are not really touching it. You see, every atom is surrounded by a shell of electrons. This electron cloud presents a rather negative face to the world. Remember that like charges repel each other. When two atoms approach each other, their electron shells push back at each other, despite the fact that each atom's net charge is 0. This is a very useful feature of nature. It makes our lives a lot easier.\n\nNow the question you should be asking is, if atoms push away from each other, why doesn't the entire universe just blow away from itself? The answer is that some, actually most atoms' electron shells are not full. When two atoms come together and have empty spaces in their electron shells, they will share electrons to fill in the spaces in both of their shells. Yes, the electrons really do go back and forth between atoms and they do so pretty fast. Electrons tend to be kind of mobile, which is also a very nice feature of nature, since without it your walkman would not work. Once both atoms' outer shells are full due to this electron sharing, they go back to their usual repulsive behavior. This, by the way, is how we get molecules and the secret to understanding Chemistry. It's all about the electrons!

Atom  \n\nThe smallest unit matter can be divided into whilst still retaining its chemical identity. Atoms are not single particles but complex arrangements of three types of particles. The subatomic particles, protons, neutrons and electrons, combine to form atoms. The protons and neutrons provide the bulk of an atom's mass and are concentrated into a tiny central region known as the atomic nucleus. The nucleus is held together by the strong nuclear force which acts between the constituent particles (termed nucleons ). The protons are positively charged and so mutually repel each other, but it is not until there are many of them that they overcome the nuclear force. Thus there is only one stable element beyond lead (Z=82). Whilst the radius of an atom is in the region of 10-10 metres, the atomic nucleus is about ten thousand times smaller at 10-14 metres. The volume surrounding the nucleus is where the electrons exist. They are much lighter than the protons and neutrons and carry a negative electrical charge. Being opposite in charge to the nucleus, the electrons are held in orbits around it by the force of electromagnetism. The electrons exist in electron orbitals around the nucleus. These orbitals are grouped into shells. Within each shell are energy levels which allow the electrons to exist in unique quantum states, depending upon their angular momentum (hence energy), in accordance with Pauli's exclusion principle . In a neutral atom the number of electrons equals the number of protons. When ionisation occurs, one or more electrons are provided with enough energy to escape the atom altogether. What remains is known as an ion because it is now positively charged and will behave in a different way chemically from neutral atom. The number of protons in the nucleus of an atom (the atomic number , Z) defines which chemical element it is. There are just over 110 known chemical elements and these can be arranged in a classification sequence known as the periodic table. The number of neutrons in any given atomic nucleus can also vary. The total number of protons + neutrons is termed the atomic mass number (A). Most atoms have a prefered number of neutrons at which their nuclei are stable. Atoms with more or less neutrons than the stable configuration are known as isotopes and will often undergo radioactive decay. The simplest of all atoms is hydrogen and is a special case which has a nucleus of one solitary proton and a single electron in orbit around it. It is the only nuclide (species of nucleus) with no neutron. A stable isotope of hydrogen is called deuterium which has one neutron in its nucleus; tritium is an unstable (radioactive) isotope of hydrogen and has two neutrons.

Fission (the term meaning spliting atoms) is only possible with certain elements (elements which are much heavier than iron) like plutonium and uranium.\n\nIn a bomb, they are exploded with very strong explosives.

if u bombard the nucleus of one element with protons or neutrons the elements can change so they are basically interchangeable while cells are at much more complex level of differentiation

Why do atoms not fly apart? After all, the nucleus is a bunch of positive charges all very close together. \n\nAnswer: the strong force holds the nucleus together.

because it takes energy, like electricity to move an electron between bands of an atom. \n\n\nall though it can be done with heat or radiation...etc, the most common unit is electron volt, all energy related to photons, neutron....are i think in electron volts too.

Atoms are the building blocks from which matter is formed. Everything around us is made up of atoms. Nuclear energy is contained within the center of the atom in a place known as the nucleus. Particles within the nucleus are held together by a strong force. If a large nucleus is split apart (fission), generous amounts of energy can be liberated. Small nuclei can also be combined (fusion) with an accompanying release of energy. Using this strong force that holds the nucleus together to produce energy is essentially what the field of nuclear power generation is about.\n  In the fission process certain heavy elements, such as some forms of Uranium, are split when a neutron strikes them. When they split, they release energy in the form of kinetic energy (heat) and radiation. The process not only produces energy but also additional neutrons that can be used to fission other Uranium nuclei and start a chain reaction.\n  In fusion, nuclei of light elements are brought together under conditions of high pressure and temperature, causing them to combine and produce new elements and energy.

CHEMISTRY I: ATOMS AND MOLECULES\nTable of Contents\nAtoms | Electrons and energy | Chemical Bonding | Chemical reactions and molecules\n\nLearning Objectives | Terms | Review Questions | Links\nAtoms | Back to Top\n\nMost of the Universe consists of matter and energy. Energy is the capacity to do work. Matter has mass and occupies space. All matter is composed of basic elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of one type of atom, for example Carbon atoms make up diamond, and also graphite. Pure (24K) gold is composed of only one type of atom, gold atoms. Atoms are the smallest particle into which an element can be divided. The ancient Greek philosophers developed the concept of the atom, although they considered it the fundamental particle that could not be broken down. Since the work of Enrico Fermi and his colleagues, we now know that the atom is divisible, often releasing tremendous energies as in nuclear explosions or (in a controlled fashion in) thermonuclear power plants.\n\nSubatomic particles were discovered during the 1800s. For our purposes we will concentrate only on three of them. The proton is located in the center (or nucleus) of an atom, each atom has at least one proton. Protons have a charge of +1, and a mass of approximately 1 atomic mass unit (amu). Elements differ from each other in the number of protons they have, e.g. Hydrogen has 1 proton; Helium has 2.\n\nThe neutron also is located in the atomic nucleus (except in Hydrogen). The neutron has no charge, and a mass of slightly over 1 amu. Some scientists propose the neutron is made up of a proton and electron-like particle.\n\nThe electron is a very small particle located outside the nucleus. Because they move at speeds near the speed of light the precise location of electrons is hard to pin down. Electrons occupy orbitals, or areas where they have a high statistical probability of occurring. The charge on an electron is -1. Its mass is negligible (approximately 1800 electrons are needed to equal the mass of one proton).\n\nThe atomic number is the number of protons an atom has. It is characteristic and unique for each element. The atomic mass (also referred to as the atomic weight) is the number of protons and neutrons in an atom. Atoms of an element that have differing numbers of neutrons (but a constant atomic number) are termed isotopes. Isotopes can be used to determine the diet of ancient peoples by determining proportions of isotopes in mummified or fossilized human tissues. Biochemical pathways can be deciphered by using isotopic tracers. The age of fossils and artifacts can be determined by using radioactive isotopes, either directly on the fossil (if it is young enough) or on the rocks that surround the fossil 9for older fossils like dinosaurs). Isotopes are also the source of radiation used in medical diagnostic and treatment procedures.\n\nNote that each of these isotopes of hydrogen has only one proton. Isotopes differ from each other in the number of neutrons, not in the number of protons.

Other isotopes are stable. Examples of radioisotopes are Carbon-14 (symbol 14C), and deuterium (also known as Hydrogen-2; 2H). Stable isotopes are 12C and 1H.\n\nCarbon has three isotopes, of which carbon-12 and carbon-14 are the most well known.

No. It is not possible for the following reasons...\n1) Water is a compound, so it can only have molecules adn not atoms.\n2) The only atoms that you will get when you break down a water molecule are two atoms of hyderogen and one of oxygen\n3) What we get thru electric lines is only electrical energy. This is transferred by the vibration of the atoms in the cables used to supply electricity. So no atoms are actually sent accross\n4) Even if all these were possible, the procedure will be extremely expensive.

Kids bits in brackets :)\n\nAn atom bomb works by firing a proton/neutron (a little part of an atom) at a mass of uranium (nuclear material) the proton goes into the uranium and eventually hits and joins with an atom of uranium, that atom is now unstable (a bit like too many people on a ladder) so to make it self stable it loses some protons (some people fall off the ladder), usually 2 or 3 (that's the bit they call fission), these fire off and hit other atoms repeating the process in a chain. if the amount of uranium is small then a lot of the protons fly out of the uranium and do nothing, however if there is enough uranium the protons are contained in the mass and break up even more atoms, leading to a catastrophic chain reaction (KaaaaBOOOOOOM)!!! \n\n***Try shouting the last part it should get a few laughs :)\n\nPS. because the uranium lost more protons than was originally put into it as extra, it is no longer standard uranium, this is called a uranium isotope.\n\nbrubeck_take5 yeah I remember the ping-pong ball video... really cool, wouldn't mind seeing that again... gonna see if I can find it... let you know :)\n\nhere goes... thing the slow motion one is the best\n\nhttp://www.ap.stmarys.ca/demos/content/modern/mousetrap_reactor/trap_sideview_slow_high.wmv\n\nbut if you want to look at them all\n\nhttp://www.ap.stmarys.ca/demos/content/modern/mousetrap_reactor/mousetrap_reactor.html
