Question

In the activity, when na lost an e- it shrank and the cl+ grew in size. does that say anything about the location of the electron before and after it was transferred?

Answer 1

Since the electron that is lost is on the valence shell of sodium, the size of sodium will shrink while the size of chlorine will increase.

Ionic bonding

Ionic bonding is said  to occur when a  metal looses an electron to a nonmetal. The resulting compound is actually an ion pair.

For the formation of sodium chloride, a sodium atom looses an electron which is present on its valence shell while chlorine accepts this electrons into its valence shell as a result, the size of sodium will shrink while the size of chlorine will increase.
