15 Οκτ 2014 · Chemists describe the shell and subshell in which an orbital belongs with a two-character code such as 2p or 4f. The first character indicates the shell (n = 2 or n = 4). The second character identifies the subshell.
The letter in the orbital name defines the subshell with a specific angular momentum quantum number l = 0 for s orbitals, 1 for p orbitals, 2 for d orbitals. Finally, there are more than one possible orbitals for l ≥ 1, each corresponding to a specific value of m l .
Electrons orbit the nucleus of an atom at different ranges, called shells. Each shell has a different energy level, increasing the further it is from the nucleus. Each energy level is given a number called the principal quantum number, n.
As shown in Table 1, the s subshell has one lobe, the p subshell has three lobes, the d subshell has five lobes, and the f subshell has seven lobes. Each of these lobes is labeled differently and is named depending on which plane the lobe is resting in.

An orbital is a space where a specific pair of electrons can be found. We classified the different Orbital into shells and sub shells to distinguish them more easily. This is also due to the history when they were discovered.
