Valence Electrons
It depends on the number of electrons in the outer valence shell in the atom
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
Electrons are involved in chemical reactions.
An electrically charged atom or group of atoms with an unpaired electron in its outermost shell is called a free radical. If the outermost shell of an atom is half-filled with electrons, that atom is most likely to share electrons.
There are 6 electrons in the outer most shell
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.

Electrons; valence electrons are on the outermost level
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
Electrons are involved in chemical reactions.
An electrically charged atom or group of atoms with an unpaired electron in its outermost shell is called a free radical. If the outermost shell of an atom is half-filled with electrons, that atom is most likely to share electrons.

These are the valence electrons.
There are 6 electrons in the outer most shell
Calcium atoms have two electrons in the s orbital of their outermost energy level. Their electron configuration is [Ar]4s2.
Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.
