All of the ________ have a valence shell electron configuration ns¹. A)noble gases B)halogens C)chalcogens D)alkali metals E)alkaline earth metals

Question

Quizplus · Accepted Answer

The valence shell electron configuration nsS1U1P11S1S1P0 indicates an electron configuration of nS1, where n is the principal quantum number of the highest energy level, and P11S1S1P0, which indicates one electron in the P subshell of the highest energy level. This configuration is typical of the alkali metals, which have one valence electron in the S subshell and one in the P subshell.
