Quantum Numbers
By Jason Angeles
Quantum numbers set of numbers that describe values of conserved quantities in the dynamics of the quantum system. Quantum numbers helps to describe elements easier and simpler and making them Easier to identify. Perhaps most peculiar aspect of quantum mechanics is the quantization of observable quantities, since quantum numbers are discrete sets of integers or half-integers. This is distinguished from classical mechanics where the values can range continuously. Quantum numbers often describe specifically the energies of electrons in atoms, but other possibilities include angular momentum, spin, etc. Any quantum system can have one or more quantum numbers; it is thus difficult to list all possible quantum numbers.
Quantum numbers are represented by 4 letters, n, l , ml, and ms.
N - Representing the highest energy level of any given substance.
L - Representing the number of subshells:
S= 0
P= 1
D= 2
F= 3
ML – Representing the last orbital an electron will be placed in.
MS – Representing if the last electron on the orbital is paired, ½ if paired and -1/2 if not
