TED-ED: How atoms bond - George Zaidan and Charles Morton

The video tutorial explains how atoms bond with each other, forming either ionic or covalent bonds. Ionic bonds occur when one atom transfers electrons to another, resulting in charged ions that attract each other, as seen in sodium chloride. Covalent bonds involve the sharing of electrons between atoms, forming molecules like proteins and DNA. The arrangement of electrons in an atom determines its bonding capacity, with elements like carbon, nitrogen, and oxygen forming multiple bonds. The video also highlights the varying sizes of molecules, from small oxygen gas molecules to large human chromosomes.
