What are Quantum Numbers? Write a brief note about each quantum number. Quantum numbers: 1)Each electron in an atom is described by a set of three numbers (n,l,m). These are Quantum numbers. 2) Quantum numbers describe the space around the nucleus where the electrons are found and also their energies. These are called atomic orbitals. The 4 Quantum Numbers are: Principal Quantum Number. The Angular momentum Quantum Number Magnetic Quantum Number. Spin Quantum Number 1) Principal Quantum number: It is introduced by Neil's Bohr.  It is related to the size and energy of the main shell.  The principal quantum number is denoted by 'n'.  If "n" increases the shells become larger and the energy increases. The Shells are also Represented by letters K, L, M...  For each 'n' value there is one main shell. 2) The angular - momentum Quantum number: It was introduced by Sommerfeld.  It has integers values from 0 to n-1 for each value of 'n'. Each (l) value repr
