This quantity describes the arrangement of electrons in an atom and provides the number of electrons in each primary and secondary energy level. Electrons fill the layers in increasing energy order. A sublevel must be completely filled before we can start filling the next sublevel. The text refers to:

A) electronic distribution.
B) atomic number - Z.
X C) quantum numbers.
D) the s, p, d, f sublevels.
E) the periodic table.
