Which name is given to a bond between atoms that results from the mutual sharing
of a pair of electrons?
cohesion
ionic
covalent
hydrogen bonding

Covalent bond

Explanation:

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.

Covalent compounds are insoluble , hard, having low melting and boiling points and have low conductivity.

i'm wiling to try and you : )
