The correct answer is....
An atom according to its atomic number arranges the electrons in the shells and when all electrons are arranged then the electron (valence electrons) in valence shell loses or gains electrons to complete octet and by doing so it gains negative or positive valency.
Gains electrons......negative charge
Lose electrons........positive charge.
Valency is based on electronic configuration.
