what is the naturally occuring element on the periodic table?
353876
If by "naturally occuring" you mean present in nature in its elemental form, then the answer includes noble gases (Helium and Argon), noble metals (Gold and Platinum and maybe Copper), and some diatomic molecules (Oxygen, Nitrogen) as well as Sulfur (S_8) and Carbon (graphite and diamond).  Most of the metals are found as some kind of oxide (in ores) or in salts (sodium chloride).  The halogens are found in salts (sodium chloride). \n\nA lot of today's useful materials were never present in significant amounts in elemental form, for example: iron, aluminum, zinc.

Synthetic elements, in chemistry, radioactive elements that were not discovered occurring in nature but as artificially produced isotopes. They are technetium (at. no. 43), which was the first element to be synthesized, promethium (at. no. 61), astatine (at. no. 85), francium (at. no. 87), and the transuranium elements (at. no. 93 and beyond in the periodic table).

Zinc is by far the best element. I also like plutonium.  It's just fun to say. "Plutonium."

The Most expensive precious metal that can be found naturally is carbon not plutonium because plutonium is man made element and can not be found naturally, the carbon most expensive precious metal ever because diamond made from that metal created by tremindous pressure,heat,and time  below the crust of the earth.

It's element 94 on the Periodic Table of Elements (see URL, below).  It's radioactive because nuclei of Plutonium atoms give off alpha and beta particles and gamma radiation in a process of radioactive decay.  The Wikipedia article on radioactive decay explains this well (URL below).

You are wrong NATURAL lead is a mixture of four stable isotopes (read NON-radioactive): 204Pb, 206Pb, 207Pb, and 208Pb . These four isotopes are the end products of each of the three series of naturally occurring radioactive elements: 206Pb for the uranium series, 207Pb for the actinium series, and 208Pb for the thorium series. Twenty seven OTHER isotopes of lead, all of which are radioactive, are recognized.\n\nLead is used as shielding because of its density. Remember that there is nothing magic about lead. Wood, air or styrofoam for that matter would work as well, but because of the density differences the same amount of shielding provided by 1" of lead might take 30" of wood or 50" of styrofoam

It's all the elements in the d-block of the periodic table. Basically, the group starting from column three to column twelve. These transition metals commonly have many oxidation states and have either partially filled d-orbitals or full d-orbitals (like mercury). They also form complex ions quite readily.\n\nIf all of that doesn't make sense, just remember it's the metals in that "lowered" part in the middle.

The most abundant element in the universe is hydrogen.  Nebulae are made up most of that and "dust".

1) is false, all the elements in living things can be found in non-living things\n\n2) this more tricky, what are these 4 elements most common in plants? I'm guessing: Hydrogen and Oxygen, (from water) Carbon, and . . .nitrogen???\nall these can be found in animals\nare you sure the question is asking about elements? elements in living things are pretty common to another. Its the compounds (hemoglobin, chlorophyll, etc) that get rather unique\n\ndo a little research, if some one cannot explain how they got the answer to a T/F question, you can't be sure they are just guessing

Common elements that exist as diatomic molecules are H, N, O, F, Cl, Br, and I.\n\nSo these elements are most commonly found in nature as H2, N2, O2, F2, Cl2, Br2, and I2.

A necessary prerequisite to the construction of the periodic table was the discovery of the individual elements. Although elements such as gold, silver, tin, copper, lead and mercury have been known since antiquity, the first scientific discovery of an element occurred in 1649 when Hennig Brand discovered phosphorous. During the next 200 years, a vast body of knowledge concerning the properties of elements and their compounds was acquired by chemists (view a 1790 article on the elements). By 1869, a total of 63 elements had been discovered. As the number of known elements grew, scientists began to recognize patterns in properties and began to develop classification schemes.

No.  Firstly, no elements are "made" on earth apart from synthetic ones.  All elemental fusion takes place in stars\n\nSecondly, only the elements up to iron are capable of being formed inside a star.  Energetically, it's the wall.  Anything with a higher atomic number than iron can only be formed under the action of a supernova explosion.  Supernovae then seed the interstellar dust with these heavier elements, which eventually coalesce under the effects of gravity to form new stars, and, presumably, planetary systems.  Given the number of new extrasolar planets found recently, this seems to be a relatively common phenomenon.\n\nSo, all the gold on Earth was formed in a supernova explosion, and when the dust particles that condensed out of that explosion gathered together to form the Earth, a small amount of gold was present.  That's where it all came from!\n\nAs Carl Sagan was fond of saying, "We are all star-stuff."

Even though there are 92 elements that are naturally found, only eight of them are common in the rocks that make up the Earth’s outer layer, the crust. Together, these 8 elements make up more than 98% of the crust. \n\nThe 8 most common elements in Earth’s crust: \n46.6% Oxygen (O)\n27.7% Silica (Si)\n8.1% Aluminum (Al)\n5.0% Iron (Fe)\n3.6% Calcium (Ca)\n2.8% Sodium (Na)\n2.6% Potassium (K)\n2.1% Magnesium (Mg)\n\nThe picture on the left shows where these elements are located within the periodic table. Together, the elements oxygen and silica make up most of the Earth’s crust and these two elements are the ingredients for Earth’s most common mineral, quartz.

A chemical element, often called simply an element, is a substance that cannot be decomposed or transformed into other chemical substances by ordinary chemical processes. All matter consists of these elements and as of 2006, 117 unique elements have been discovered or artificially created. The smallest particle of such an element is an atom, which consists of electrons centered about a nucleus of protons and neutrons.

pull out your periodic table and this becomes very easy.  elements have an oxidation # of 0.
