Basically what the Wiki User is saying:
They act as codes that provide information about each electron in an atom.
n - energy level (can be 1,2,3…)
l - orbital shape (s=0, p=1, d=2)
ml - orbital orientation (goes from -/to +/by integers)
ms - spin (arrow up or down, and can be either +½ or -½)
Quantum numbers are the sets of numerical values which satisfies Schrodinger wave equation. There are four quantum numbers:
Principal quantum number(n) showing number of shells available
Azimuthal quantum number(l) showing orientation of the orbitals
Magnetic quantum numbers(m) showing number of degenerate orbitals
Spin quantum number(s) showing clockwise and anti clockwise spin of electrons
http://en.wikipedia.org/wiki/Quantum_number
These are: principal quantum number (n), azimutal quantum number (ł), magnetic quantum number (m), spin quantum number (sd).
3s has a principle quantum number of n=3 5s has a principle quantum number of n=5
n-1 is the max l
By azimuthal quantum numbers.
What are the quantum numbers of Br?
from Max Planck's theory, quantum numbers are units of energy.
All four quantum numbers i.e principle ,azimuthal or subsidiary, magnetic and spin quantum numbers are required to specify a single atomic orbital.

Principal quantum numbers (n).
The first three quantum numbers (principle, angular momentum, magnetic) are all whole numbers. The last quantum number (spin) is either ½ or -½.

The four quantum numbers, n, l, m1, and ms, are all solutions to Schrödinger's equation. These numbers are used to assign each electron in an atom an "address." They "uniquely characterize an electron and its state in an atom" ("Quantum Number").
