Calculate the energy required for the process He+(g) → He2+(g) + e-



Q.34:- Calculate the energy required for the process
He+(g) → He2+(g) + e– 
The ionization energy for the H atom in the ground state is 2.18×10-18 J atom-1.

 

 

Answer:-



 
For H-like particles, E= – (2π2mZ2e4/n2h2)
For H-atom, I.E. = E-E= 0 – (-2π2m×22×e4/12×h2)
= (4×2π2me4/h2) = 4×2.18×10-18 J = 8.72×10-18 J
