atomic number 2- a very light colorless element that is one of the six inert gasses; the most difficult gas to liquefy; occurs in economically extractable amounts in certain natural gases (as those found in Texas and Kansas) He,helium ...
Average atomic mass of an element is calculated by considering the weighted average of all naturally occurring isotopes of an element. By multiplying the mass number times the percent abundance and determining the weighted average, the average atomic mass can be found.What...
atomic number 10 - a colorless odorless gaseous element that give a red glow in a vacuum tube; one of the six inert gasses; occurs in the air in small amounts Ne, neon chemical element, element - any of the more than 100 known substances (of which 92 occur naturally) that cannot be...

Atomic number is the number of protons in an atom's nucleus. It is the same for all atoms of a given element. What is the atomic number? The atomic number of a given element is the number of protons contained in the nucleus of an atom of that element. Is mass number A or Z?
To determine which of the statements regarding noble gases is incorrect, we will analyze each statement step by step.Step 1: Analyze the first statement Statement: Argon is used in higher temperature metallurgi
The sequential filling of these orbitals accounts for the periodic chemical behavior of the elements with their atomic number. Full orbitals are inherently stable, and the resulting atoms are chemically unreactive. These correspond to the noble gases, helium (He), neon (Ne), argon (Ar), ...
of noble-gas reactivity, xenon compounds, including halides, oxides, oxofluorides, oxo salts, and numerous covalent derivatives with a number of compounds covalently bonded to other polyatomicligands, have been synthesized and structurally characterized. As might be predicted from the position of xenon...

Now simply multiply each element's joules per fissioned atom by the number of atoms per gram and you'll have the amount of joules produced by totally burning the entire gram of nuclear fuel. For example: Uranium-235 produces 3.244×10-11joules per fission, times 2.5626135×1021atoms per gra...
