Complete the following:
(i) Metals: Form positive ions
(ii) Nonmetals: ____________
1. Cation
A cation is a chemical species that carries a positive charge and is formed by losing the electrons of an atom.
Metals are highly electropositive and lose electrons easily and form cations.
2. Anion
An anion is a chemical species that carries a negative charge and is formed by gaining electrons by an atom from the other species.
Nonmetals gain electrons and form anions.
(i) Metals: Form positive ions.
(ii) Nonmetals: Form anions
