For the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³, choose the appropriate number of valence electrons present from the response list.

Question

Quizplus · Accepted Answer

The valence electrons are the electrons present in the outermost shell. In this configuration, the outermost shell is the 4th energy level, which contains the 4s, 4p, and 4d orbitals. Counting the electrons present in the 4s and 4p orbitals gives a total of 5 valence electrons. Therefore, the best choice is C) 5 valence electrons.
