Answer:

C. Two oxygen atoms

General Formulas and Concepts:

<u>Types of Bonds</u>

  • Covalent Bonds - forms between 2 non-metals
  • Ionic Bonds - forms between a non-metal and a metal
  • Metallic Bonds - forms between 2 metals

Explanation:

Any metal forming a compound with an non-metal is an ionic bond. Therefore, A and D are incorrect.

  • Fe (Iron) is a Transition Metal forming an ionic bond with O (Oxygen), a non-metal.
  • Na (Sodium) is a Alkali Metal forming an ionic bond with Cl (Chlorine), a non-metal.

Any 2 metals forming bonds with each other is a metallic bond. Therefore, B is incorrect.

  • Na forms a metallic bond with Na.

Any 2 non-metals forming bonds with each other is a covalent bond. There are 2 types of covalent bonds: non-polar and polar.

  • O forms a covalent bond with O.

Therefore, our answer is C.
