Why do covalent compounds share electrons?

This video tutorial explains how to identify covalent compounds, which form when electrons are shared between two nonmetals or anions. It highlights the importance of electronegativity in electron sharing and provides methods to identify covalent compounds. The video also includes examples and discusses exceptions like hydrogen, which, despite its position on the periodic table, is a nonmetal.
