Energy level n = 1 has only 1 sublevel: an s orbital. Energy level n = 2 has 2 sublevels: the s and p orbitals. Energy level n = 3 has 3 sublevels: the s, p, and d orbitals. Energy level n = 4 has 4 sublevels: the s, p, d, and f orbitals. Each atomic orbital is designated by the principal quantum number followed by the letter of the sublevel.
