Both. Atoms bond because one atom has extra electrons and another atom has too few so they meet up and balance out
ionic bonding :]
When atoms lose and gain electrons, an ionic bond will form. When atoms share electrons, a covalent bond will form.
Actually both. Atoms gain electrons to form negatively charged anions whereas when atoms lose electrons positively charged cations are formed. Ionic bond is the force of attraction between cations and anions
do atoms of a covalent bond lose r share electrons
They need to gain them.
Atoms that join by a covalent bond share electrons but do not gain or lose them. In a covalent bond, the electrons are shared between the atoms, creating a stable electron configuration for both atoms involved.
nonmetals
They will loose electrons.
Atom loose or gain electron to make its octet complete. It is done to achieve inert state.
ions
An ionic bond.
To form a molecule, atoms can share, lose, and gain electrons
