In chemistry and atomic physics, an electron shell, or a principal energy level, may be thought of as an orbit followed by electrons around an atom's nucleus. Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight $(2+6)$ electrons, the third shell can hold up to $18(2+6+10)$ and so on. Each shell consists of one or more subshells, and each subshell consists of one or more atomic orbitals. Each subshell is constrained to hold $4 \ell+2$ electrons at most, namely:

Each $s$ subshell holds at most $2$ electrons( $1$ orbital)
Each $p$ subshell holds at most $6$ electrons( $3$ orbitals)
Each $d$ subshell holds at most $10$ electrons( $5$ orbitals)
Each $f$ subshell holds at most $14$ electrons( $7$ orbitals)
Each $g$ subshell holds at most $18$ electrons( $9$ orbitals)
