What is ground state and excited state of an electron?

Explain the meaning of ground state and excited state of an atom?

The ratio of the areas of the circular orbits of an electron in the ground state that of the first excited state of an electron in the hydrogen atom is

(a)Show that the ratio of velocity of an electron in the first Bohr orbit to the speed of light c is a dimensionless number. (b) Compute the velocity of electrons in ground state, first excited state and second excited state in Bohr atom model.
