1․1 What is Covalent Bonding?
Covalent bonding is a chemical process where atoms share one or more electrons to form a stable molecule․ This type of bond typically occurs between non-metal atoms‚ as they seek to achieve a full valence shell by sharing electrons․ Unlike ionic bonds‚ which involve the transfer of electrons‚ covalent bonds rely on mutual sharing․ The shared electrons form a strong attractive force between the nuclei of the bonded atoms‚ creating a covalent compound․ This bonding mechanism is fundamental in understanding molecular structures and chemical reactions․
