1. a chemical bond between atoms with similar electronegativities - covalent bond

2. a measure of the ability of an atom to attract electrons within a chemical bond - Electronegativity

3. a bond between atoms of greatly differing electronegativities - Ionic bond

4. the bond formed in metals, holding metals together - Metallic bond

Explanation:

Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking place in the bond. It is generally formed between the atoms with similar electronegativity values.

Ionic bond is the bond which is formed between the two oppositely charged ions and are held by the strong electrostatic attraction. This is formed between the atoms which have high differing electronegativities.

Electronegativity is the tendency of the atom in a covalent bond to attract the shared pair of electron towards itself.

Metallic bond is the bond which is formed by electrostatic attraction force between the positively charged metal ions and the conduction electrons.
