Successive ionization energies data of a 3rd period elements in eV/atom is
| IE1 | IE2 | IE3 | IE4 | IE5 | IE6 | IE7 | IE8 | IE9 |
| 10.49 | 17.77 | 30.20 | 51.44 | 65302 | 220.42 | 309.60 | 372 | 424.4 |
The group number of the element in long form of periodic table [as per 1 – 18 convention] is______.
detailed solution
