The correct answer to how electron movement is related to the bonding in sodium chloride is:

B. The losing or gaining of electrons will cause the created ions to be drawn towards each other to create an ionic bond.

Explanation:
1. In the case of sodium chloride (NaCl), sodium (Na) loses one electron to become a positively charged ion (Na+), while chlorine (Cl) gains one electron to become a negatively charged ion (Cl-).
2. The transfer of electrons from sodium to chlorine leads to the formation of oppositely charged ions.
3. These charged ions are then attracted to each other by electrostatic forces, forming an ionic bond between sodium and chlorine.
4. The attraction between the positive and negative ions holds the compound together in a crystal lattice structure, creating sodium chloride.

This process of electron transfer and the subsequent attraction between oppositely charged ions is what leads to the formation of an ionic bond in sodium chloride.
