Problem: In the electron configuration [Xe]6s24f145d106p4, which are valence electrons? A) all of the electrons after the [Xe] B) only the 4f14 electrons C) only the 6p4 electrons D) 6s2 and 6p4 electrons

FREE Expert Solution

The electron configuration describes the distribution of electrons within its orbitals. The electron configuration gives the principal quantum number (n), the sub-shell (l) and the number of electrons in the subshell (x)



n = 1

subshell = s → 0

electrons = 2

Valence electrons are electrons found in the outermost shell.

These are the electrons that are
