The Role of Electrons in Chemical Bonding

The video tutorial explains the bonding of atoms to form complex structures. It covers atomic structure, ionic bonding, covalent bonding, and metallic bonding. Atoms are neutral with equal electrons and protons. Ionic bonds form when metals lose electrons and non-metals gain them, creating ions. Covalent bonds occur when non-metals share electrons. Metallic bonding involves a sea of delocalized electrons around metal ions, giving metals their properties.

How do non-metals form covalent bonds?

Illustrate the concept of shared electron pairs in covalent bonding with an example.

What is metallic bonding and how does it differ from ionic and covalent bonding?
