Name two events involving electrons that can result in the formation of chemical bonds between atoms.
Alona [7]

Explanation:

Two events involving electrons are gain and loss of electrons.

When there is gain or loss of electrons between two atoms then it results in the formation of ionic bond.

Whereas when there is sharing of electrons between two atoms then it results in the formation of covalent bond.

Therefore, the chemical bonds formed can be ionic or covalent bonds.
