Elements that have five electrons in the highest-energy p sublevel in their ground state are called ________.
A)alkali metals
B)alkaline earth metals
C)halogens
D)noble gases
E)transition metals

Question

Quizplus · Accepted Answer

This is because the highest-energy p sublevel has a capacity of 6 electrons, and halogens only have 5 electrons in this sublevel in their ground state. Alkali metals have only 1 electron in the highest-energy s sublevel, alkaline earth metals have 2 electrons in the highest-energy s sublevel, noble gases have a full highest-energy p sublevel, and transition metals have partially filled d sublevels.
