Give the expression for Bohr magneton.

State the relation between orbital magnetic moment of an electron and its angular momentum. Hence find the expression for Bohr Magneton.

Using Bohr's postulates obtain the expression for Bohr radius .

The Bohr magneton is

Explain how an atom behaves as a magnetic dipole. derive an expression for the magnetic dipole of the atom. Also define Bohr magneton.

Using Bohr's postulates of the atomic model. Derive the expression for radius of nth electron orbit, thus obtaining the expression for Bohr's radius.

Using Bohr's postulates of the atomic model, derive the expression for radius of n-th electron orbit. Hence obtain the expression for Bohr's radius.

Unit of Bohr magneton is …..
