Question

An energy of 24.6 eV is required to remove one of that electrons from a neutal helium atom. The enegy (in eV)required to remove both the electrons from a netural helium atom is

Answer 1

Answer:

The enegy (in eV)required to remove both the electrons from a netural helium atom is. Solution : After the removel of first electron remaining atom will be hydrogen-like atom. ∴ Total energy required =24.6+54.4=79eV
