Overview of Cobalt Atomic Number:27 Group: 9 Period: 4 Series: Transition Metals
Germamium is in period 4 and group 4. It is in period 4 because it has 4 shells that hold electrons. It is in group 4 because it has 4 electrons in its outer shell.
The period number is the same as the energy level containing the valence electrons. For example, in period 4, the valence electrons are the 4s and 4p electrons.
