Atoms that gain electrons are called anions, and atoms that loose electrons are called cations
Since electrons are negative, they get a negative charge.
metals
an ionic bond forms
Metals lose electrons, nonmetals gain electrons.
no chemical reaction takes place . when electrons are shared it is known as covalent bond
Since electrons are negative, they get a negative charge.

A covalent bond involves the sharing of electrons between atoms. This type of bond forms when atoms share pairs of electrons to achieve a stable electron configuration.
A covalent bond forms when electrons are shared between atoms. In this type of bond, atoms share one or more pairs of electrons to achieve a stable electron configuration.
ions. (atoms that have lost or gained electrons)
The type of bond that forms between atoms or compounds is determined by the electronegativity difference between the atoms involved in the bond. If the electronegativity difference is small, a covalent bond forms, where electrons are shared. If the electronegativity difference is large, an ionic bond forms, where electrons are transferred.
A polar covalent bond forms when atoms in a molecule do not share their electrons equally. In this type of bond, the electrons are attracted more strongly to one atom, creating partial positive and negative charges on the atoms involved.

Atoms NEVER lose protons, just electrons.
