When the first electron which is most loosely bound is removed, thr amlint of energy required is less. Which tells us that first ionisation energy should be not that high. As the successive electrons are removed, the element looses it's valence electrons one by one and at some point attains noble gas configuration or fullly filled shell. In that scenario, now the electron need a greater amount of energy to get removed, which tell us that the ionisation energy for that electron which have a sudden higher value than previous ionisation energy. Here, the third ionisation energy is suddenly higher than second ionisation energy which tells us that 2 electrons where in valence shell and got removed easily. The third valence electron was in full octet shell hence needed higher ionisation energy. Therefore, we can say that this element belong to group 2A.

A space probe identifies a new element in a sample collected from an asteroid. Successive ionization energies, in attojoules per atom, for the new element are given in the table. 1 12 13 | 0.507 | 1.017 | 4.108 14 5.074 15 16 6.147 | 7.903 17 8.294 | To what family of the periodic table does this new element probably belong? 18 (8A) O 1 (1A) 16 (6A) 14 (4A) 15 (5A) 13 (3A) 17 (7A) O 2 (2A)
