Question

The element having highest I.P. in the two series C,
N. O and Si, P. S:-
(1) P (2) N (3) S
(4) O​

Answer 1

Answer:

(a) F>O>N>C (second ionization potential. (b) N>Si>C>P (electronegativity of the elements) (c)Na>Me>Al>Si (First ionization potential).Li has the highest IE2 , because to remove the second electron we must break the stable 1s2 noble gas shell.

Magnesium has fully filled s orbital and thus first ionization potential is higher . Thus, first ionization potential will be higher. After loss of one electron, the second electron will be lost easily as it will acquire inert gas configuration after loss of second electron. Thus 2nd IP < 1st IP for magnesium.

hope it is helpful

Answer 2

Answer:

Nitrogen having heighest ionization potential because ionization potential increases left to right and decrease down the group...............
