A sodium atom can react with a chlorine atom and form an ionic bond. Which statement related to their ionic bond must be true?

*Both of the atoms share their electrons.

*Sodium and chlorine bond to form very large structures.

*The bond that is formed is the strongest type of chemical bond.

*One of the atoms donates an electron to the other atom.

Answer: Option (d) is the correct answer.

Explanation:

An atom that donates an electron to another atom will lead to the formation of a bond known as ionic bond.

For example, atomic number of sodium is 11 with electronic distribution 2, 8, 1. Atomic number of chlorine is 17 with electronic distribution 2, 8, 7.

So, in order to stabilize both sodium and chlorine, sodium will donate its valence electron to the chlorine atom. This will form an ionic bond between sodium and chlorine.

Thus, we can conclude that the statement one of the atoms donates an electron to the other atom, must be true.

One of the atoms donates an electron to the other atom
