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)
1 s 2
n = 1
subshell = s → 0
electrons = 2
Valence electrons are electrons found in the outermost shell.
These are the electrons that are

B) only the 4f14 electrons
C) only the 6p4 electrons
D) 6s2 and 6p4 electrons
