Answer:
D
Explanation:
Covalent bonding occurs when metallic element like sodium transfers an electron to a non-metallic element like fluorine. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability
