We are asked to determine the Lewis symbol for the ions in the ionic compound SrBr2
First, let’s determine the valence electrons of the elements in SrBr2
Recall: The group number of representative elements corresponds to their valence electrons
• Strontium, Sr is from group 2A → 2 valence electrons
• Bromine, Br is from group 7A → 7 valence electrons
Select the Lewis symbols for the ions in each ionic compound.
