Show the determination of the charge on the ion formed by
the Mg12
atom.
Your Answer:
Mg12 is a METAL. --> Mg+2 = losing 2e.
This means that we are going to be LOSING
electrons. The subshell configuration is as follows:
1s2 2s2 2p6 3s2
Since we are losing electrons, we will drop the outer shell (3s2 )
which holds 2 electrons. Thus, we are LOSING 2 ELECTRONS.
