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.
