Question

The energy needed to remove the one electron from neutral helium atom is 24.6 eV. Then the energy needed to remove both the electrons from neutral helium atom is (A) 79.0 eV (B) 51.8 eV (C) 49.2 eV (D) 38.2 eV

Tardigrade Admin · Accepted Answer

E=13.6× ((Z)2/1)=54.4eV Total energy =24.6+54.4=79 text eV

Q. The energy needed to remove the one electron from neutral helium atom is $24.6 e V$ . Then the energy needed to remove both the electrons from neutral helium atom is

79.0 eV

51.8 eV

49.2 eV

38.2 eV

$E = 13.6 \times \frac{( Z ) ^{2}}{1} = 54.4 e V$ Total energy $= 24.6 + 54.4 = 79 e V$

Q. The energy needed to remove the one electron from neutral helium atom is 24.6eV. Then the energy needed to remove both the electrons from neutral helium atom is
