• I can determine the electronic configuration of elements and their ions. 
• I can state that: (a) Group VIII noble gases have a full outer shell (b) the number of outer shell electrons is equal to the group number in Groups I to VII (c) the number of occupied electron shells is equal to the period number.

I THINK I NEED MORE PRACTICE ON:
1. I can determine the electronic configuration of elements and their ions.
2. I can state that: (a) Group VIII noble gases have a full outer shell (b) the number of outer shell electrons is equal to the group number in Groups I to VII (c) the number of occupied electron shells is equal to the period number.
