A metal ion M2+ has a single electron. It requires radiation with a frequency of 2.96x10^16 Hz (s^-1) to remove the electron from the ground state. Identify the ion.

Energy = h(plank constant ) * frequency

= 6.626*10^-34* 2.96*10^16

= 1.96*10^-17 joules

In electron volt = 122.5 ev

Now ground level means n= 1

So( 13.6*Z^2 ) /n^2 = 122.5

Z = atomic no. Of the atom

Z = 3

Means Li2+ is present
