The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Argon–along with helium, neon, xenon, radon, and krypton–belongs to the so-called “noble” gases. Also called inert gases, they have complete outer electron shells and were believed not to react with other elements or compounds.

One atom of each element is made up of protons, neutrons, and electrons. The number of electrons determines how an element reacts. Look at the different groups for clues to how the elements will react. Noble Gases usually do not react because they do not tend to gain or lose electrons.

Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the “inert gases” due to the fact that their filled valence shells (octets) make them extremely nonreactive.

Tin

The carbon family, Group 14 in the p-block, contains carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl)….Introduction.

The general electronic configuration of group 14 elements is ns2np2. There are two electrons in the outermost p orbitals of these elements. The electronic configuration for each element of this group is given below. Lead [Xe]4f14 5d10 6s2 6p2.
