Answer:

Hello friend,

Explanation:

En = -13.6 eV/n2. Here n is called the principle quantum number. The values En are the possible value for the total electron energy (kinetic and potential energy) in the hydrogen atom. The average potential energy is -2*13.6 eV/n2 and the average kinetic energy is +13.6 eV/n2.

Answer:

ANSWER

Energy levels in Hydrogen like atom is given by E=−13.6

n

2

z

2

eV

As He

+

is 1

st

excited state

∴z=2, n=2

E=−13.6 eV

As total energy of He

+

in 1st excited state is −13.6 eV, ionisation energy should be +13.6 eV.
