Compare and contrast ionic, covalent, and metallic bonds. identify at least one similarity or difference between each pair of bond types (ionic-covalent, ionic-metallic, metallic-covalent).

Both covalent and metallic bonds involve the sharing of electrons. Ionic bonds involve loss or gain of electrons.

Both covalent and metallic bonds can form between atoms of the same element. Ionic bonds form only between atoms of different elements.

Both ionic and covalent bonds can involve nonmetals. Metallic bonds involve only metals.

Both ionic and metallic bonds can involve metals. Covalent bonds typically involve only nonmetals.
