The successive ionization energies in KJ/mol of an element P are 740, 1500, 7000, 10500, 13600, 18000 and 21700. Which ion is the most likely to be formed when P reacts with chloride?
Sudden abrupt change in IP values was observed from second I.P to the third I.P . The aspect indicates that the element belongs to group II.
Therefore the ion formed will be P+2
