Question

the valence shell electrons of an atoms ar​

Answer 1

Answer:

In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Answer 2

Explanation:

In an atom, the electrons spin around the center, also called the nucleus. The electrons like to be in separate shells/orbitals. ... That means there are 18 electrons in an argon atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and eight in shell three.
