What kind of bond would form between an iron and an oxygen atom: ionic, covalent, or metallic? What kind of bond would form between two silver atoms: ionic, covalent, or metallic? What happens to the valence electrons in this bond? How do ionization energy and electronegativity help explain why this occurs? 3) What kind of bond would form between two chlorine atoms: ionic, covalent, or metallic? What happens to the valence electrons in this bond? How do ionization energy and electronegativity help explain why this occurs?

Since iron is a metal and oxygen is a non metal, a bond is formed between the two when electrons are transferred from iron to oxygen. Hence the bond is ionic.

Two silver atoms are held together by metallic bonds. Metallic bond are bond forces that exist between metal atoms in a crystal lattice. The valence electrons in this bond form a cloud. Metals have low ionization energy and low electronegativity hence they loose electrons easily. This accounts for the nature of the metallic bond.

The bond formed between two chlorine atoms is a covalent bond. The valence electrons in this bond are localized between the two chlorine atoms. Chlorine is a nonmetal hence it has a high ionization energy and high electronegativity. Hence it forms covalent bonds in which electrons are shared between bonding atoms.
