Sodium and chlorine react and an ionic bond forms. which statement is true about the bonding that has occurred? a. the sodium atom has lost an electron and the chlorine atom has gained one. b. the sodium and the chlorine atoms have both gained an electron. c. the sodium and the chlorine atoms have both lost an electron. d. the chlorine atom has lost an electron and the sodium atom has gained one.

A: The sodium atom has lost an electron and the chlorine atom has gained one.

Explanation:

Sodium wants to lose an electron and chlorine wants to gain an electron to become stable. This is because of their place in the periodic table, sodium being on the very left edge and chlorine on the very right (noble gasses dont count as they are stable to begin with)

Therefore sodium will donate to chlorine so they both become stable with an ionic bond.
