The ionisation energy of `10` times innised sodium atom is

The ionization energy of 10 times the ionized sodium atom ......

The ionisation energy of the ionised sodium atom Na^(+10) is:

The ionisation energy of hydrogen atom is 13.6 eV , the ionisation energy of a singly ionsed helium atom would be

Calculate the energy required for the process He^(+)(g) to He^(2+)(g)+e The ionisation energy of the H-atom in the ground state is 2.18xx10^(-18)J"atom"^(-1) .

Calculate the energy required for the process He ^(+) (g) to He ^(2+) (g) + e ^(-) The ionisation energy for the H-atom in the ground state is 2. 18 xx 10 ^(-18) J "atom" ^(-1).
