Ah, let's paint a lovely picture of electron dot notation for phosphorus and strontium. Phosphorus has 5 valence electrons, so its notation is P with 5 dots around it. Strontium has 2 valence electrons, so its notation is Sr with 2 dots around it. Remember, each dot represents an electron sharing its positive energy with the world.
The ionic notation for Bromine is Br-. It gains one electron to form Br-
