Describe covalent compounds

Covalent compounds are formed when atoms, typically non-metals, share electrons to form chemical bonds. This sharing allows each atom to achieve a more stable electron configuration, often resembling that of a noble gas. The resulting molecules have distinct properties, such as lower melting and boiling points compared to ionic compounds, and they may not conduct electricity. Examples include water ($\text{H}_2\text{O}$), methane ($\text{CH}_4$), and ammonia ($\text{NH}_3$).
