4.14 Use Lewis symbols to show electron transfer between the following atoms to form cations and anions :
We have the electronic configurations of both:
having 3 electron in the valence shell, and it can donate 3 electron to get to the nearest noble gas configuration.
having 3 electrons in the valence shell, and it wants to complete its octet by accepting 2 more electrons.
So, there will be electron transfer between them as follows:
