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...

Bohr's Atomic Model, Bohr's - Sommerfeld Atomic Model, Quantum Mechanical Model | Structure of Atom Class 10 | Part 3 You can watch the video before going to read the article about Bohr's atomic model, Bohr-Sommerfeld atomic model, Quantum mechanical modal.   What the main postulates of the Bohr's atomic Model of a Hydrogen atom? Main Postulates of Bohr's Model of a Hydrogen Atom: The following are the main postulates of the Neils Bohr's Atomic model of a Hydrogen atom, Electrons in an atom occupy stationary orbits (energy levels) of fixed energy at different distances from the center called the nucleus. When an electron jumps from a lower energy state to a higher energy state, it absorbs energy and emits energy when such a jump occurs from a higher energy level (state) to lower energy level (state). The energy of an electron in an atom can have only certain values E1, E2, E3,... i.e. the energy is quantized. The states corresponding to these energies are called...
