• First

• Second

For an element with the last orbital as P, how do you determine its group number?

• Add electrons in P and F orbitals

• Add electrons in S and D orbitals

In the case of zinc, why do we not add electrons in D and S orbitals to find the group number?

• Because P orbital is complete

• Because D orbital is incomplete

• Because D orbital is complete

• Because S orbital is empty
