Why is Xenon so unreactive?

Xenon is a member of the zero-valence elements that are called noble or inert gases. It is inert to most common chemical reactions (such as combustion, for example) because the outer valence shell contains eight electrons.

Why is an atom unreactive?

When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . Atoms of group 0 elements already have stable arrangements of electrons. This means that they have no tendency to lose, gain, or share electrons. This is why the noble gases are unreactive.

Is Lead heavier than gold?

Gold is much heavier than lead. It is very dense. ... Therefore gold weighs 19.3 times as much or (19.3 x 8.3 lb) about 160 pounds per gallon. Although gold has a density 19.3 times greater than water and is one of the most dense substances on Earth, there are substances with far more amazing densities.

Can gold be man made?

Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements. ... Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. May 2, 2014

Why is lead more common than gold?

So to narrow down and answer your question: Lead (Pb) tends to be more abundant than Gold (Au) because it has an even number of protons in its nucleus (82 versus 79) and its inner electron shells are filled (Basic Metal versus Transition Metal).
