Canvas Classes · Accepted Answer

Strategy:
 A jump between  and  means the element has 2 valence electrons and loses its  electron from a stable inner shell.

Step 1: Identify configuration with 2 valence electrons
- (a) : Magnesium. Has 2 valence electrons.  and  are from the  subshell.  comes from the stable  noble gas core. (Matches)
- (b) : 1 valence electron (Jump at ).
- (c) : 3 valence electrons (Jump at ).
- (d) : 4 valence electrons (Jump at ).
