Question

Draw a set of diagrams to explain, in terms of electrons, what occurs when potassium and oxygen react together.

Answer 1

I will explain what occurs between potassium and oxygen to form K2O.

K has 1 electron in the outer shell and O has 6. As O has 6 electrons, to get the Octet, we need 2 potassium. This compound (K2O) is ionic.
