# As One Considers Orbits with Higher Values of N in a Hydrogen Atom, the Electric Potential Energy of the Atom - Physics

MCQ

As one considers orbits with higher values of n in a hydrogen atom, the electric potential energy of the atom

#### Options

• decreases

•  increases

•  remains the same

• does not increase

#### Solution

increases

The electric potential energy of hydrogen atom with electron at the nth state is given by

V = - (2xx13.6)/n^2

As the value of n increases, the potential energy of the hydrogen atom also increases, i.e. the atom becomes less bound as n increases.
