Question

Which group does this element belong to? The successive ionization energies are listed in below:

235 kJ, 683 kJ, 1827 kJ, 10456 kJ, 12789 kJ

Answer 1

Group 3

Step-by-step explanation:

Because there is a huge gap of difference of ionization energies between 1827kJ and 10456kJ. The first 3 electron can be easily removed, while the fourth electron is hard to remove as it comes from an inner level
