noble gases (or inert gases)
gas mpl inputs

Inert gases. These elements are found in Group 0 of the periodic table, and they are all highly non-reactive monatomic gases found in the atmosphere in small quantities. They are: helium, neon, argon,

The electronic configuration of these gases is very stable, and the elements do not show any tendency to lose or gain electrons. Therefore, it is difficult for them to form compounds. There are compounds of the most massive of these elements, such as XeFa, but these compounds are rare.


noble gas structure (or inert gas struc- ture)

Structure of the gas input

Structure of inert gas Inert gases are stable, non-reactive elements due to their electronic configurations. They have eight electrons in their outer shell configurations. This is a stable configuration because the eight electrons completely fill part of the shell so that:
It is difficult to add another electron or remove one. When elements form electrolytes, the formed electrolytes have an inert gas configuration.

nonmetal
non metal m

No metal. Elements have (a) one of two molecular structures, and therefore they are either gases at room temperature or they are solids or liquids with low melting and boiling points, or they have (b) giant structures with Cova lent bonding The traditional properties of metals are:

Poor conductivity.
It does not react with acids.
Produces acidic oxides.
Form covalent compounds.
Stalagmites produce anions.

Examples:

Halogens, inert gases, oxygen,
Sulfur, carbon, nitrogen.
