For example, let's take ammonia (NH3), which has one unshared pair.
If it is placed in an acidic solution (a proton donator), H+ ions (protons), the ammonia takes in the proton and becomes NH4+, an ammonium ion. The H+ ion has a vacant 1s orbital in its valence shell and can accomodate two electrons. The two unshared pair of electrons in the ammonia can be donated to the H+.
An arrow from the nitrogen atom to the hydrogen ion indicates that the nitrogen is sharing it pair of electrons with it. This sharing is called an coordinate covalent bond.

Nitrogen is trivalent. How its valency could be 4 ?
