The Representative Elements
Elements in groups 1A through 7A: representative elements
The group number equals the number of electrons in the highest occupied energy level.

6. Blocks of Elements 6.2 Transition Elements
This diagram classifies elements into blocks according to sublevels that are filled or filling with electrons. Interpreting Diagrams In the highest occupied energy level of a halogen atom, how many electrons are in the p sublevel?
