Question

What are inert elements? Explain in detail.

Answer 1

inert elements are those elements which do not react with other elements.
they are just like inert gases. examples are Krypton, xenon,etc.

Answer 2

An inert gas is a gas that is generally non-reactive with other substances. The term inert means non-reactive. We refer to gases as being chemically inert if their atoms don't combine with other atoms in chemical reactions.
When we refer to inert gases, we are usually referring to six primary ones, also called the noble gases. Meet the most common inert gases: helium (He), argon (Ar), neon (Ne), krypton (Kr), xenon (Xe), and radon (Rn). Another noble gas, element 118 (Uuo), does not occur naturally. 'Wait a minute', you think, 'I've heard of krypton! Isn't that the planet that Superman calls home?' It is, according to the comic books, and presumably the planet got its name from the element.

Why Are Some Gases Inert?
Atoms are considered to be unstable if they do not have a filled outer orbital. For atoms with an atomic number greater than 5, the 'magic number' for filling the outer orbital is 8. For smaller atoms (atoms with atomic numbers less than 5, like helium), the outermost orbital is filled with 2 electrons. An electron orbital is the location where electrons reside. Most atoms do not have 8 electrons in this outer orbital so they react with other atoms to form bonds to fill their outer electron orbital. The atomic structure of the noble gases is different from the structure of most atoms because they have a filled outer orbital. Because of this, they are stable and do not 'need' to interact with other atoms. Note that one of the noble gases, helium, is a very small atom and has only 2 electrons in its outermost electron orbital (which is its only orbital). It is stable with this filled outer orbital. As you just learned, several inert gases are commonly known as the
noble gases . Just as noblemen in medieval times did not socialize much with the common folk, the noble gases do not 'socialize' or react with other substances. noble gases are chemically non-reactive most of the time.
