this is for atoms of elements combine by sharing electrons or by the complete transfer of electrons from one atom to another. What is the term?

Chemical bond

Explanation:

A chemical bond is the force of attraction that keeps the atoms or ions together in a molecule or compound. when a bond is formed the energy is stored in it and the similar amount of energy is required to break that bond.

The bond which is formed by the sharing of electrons is called as covalent bond. In covalent bond the atoms which have partially filled valence shell are combined to fulfill their valence shell (Duplet and Octet rule) to obtain stability. The force of attraction is created between the shared electrons and nucleus of each bonded atom in covalent bond.

The bond which is formed by complete transfer of electron is known as ionic bond. In ionic bond the donor atom donate its electron to acceptor atom to obtain two or eight electrons in their valence shells. The electrostatic force between opposite charges binds the two atoms in ionic bond.
