Consider the successive ionisation energy for an element 'A'. IE1, IE2, IE3, IE4, IE5 are 100 eV, 150 eV, 181 eV, 2000 eV, 2200 eV. Select correct statement(s) for element 'A' :

Question

Prashant Kotian · Accepted Answer

Correct answer: A,B,C,D. According to the values of I.E. given it can be concluded that IE1 < IE2 < IE3 <<< IE4 < IE5. This shows that it achieved stable noble gas configuration after removing three e-. It belongs to 13th group of periodic table. It could be metal or non-metal or metalloid. It forms stable trivalent cation.
