2.1 Atomic Theory
... Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy. The first shell has only an s subshell; the second shell has an s and a p subshell; the third shell has s, p, and d subshells, and the fourth has s, p, ...
