Argon (Ar):
18 electrons confugered in three shells (no. 1, 2, 3): (2, 8, 8)
and with sub-shells (s and p): (1s2, 2s2 2p6, 3s2 3p6)
As a neutral atom (When it is not an ion) the element argon has eighteen electrons.
Oxygen is a non metal element. There are 8 electrons in a single atom.

Electrons are the particles that circle the nucleus of an atom.
An atom that loses one or more electrons is an ion, specifically a cation.
Electrons in the outer most shell are called Valence Electrons.
Fluorine is the name of the element and has 9 electrons. Fluoride is the name of the halide ion, carries a 1- charge and has 10 electrons.
