Question

what is the order of increasing ionisation enthalpy of Na K N and O?​

Answer 1

Answer:

Na→N→K→O

Explanation:

Na=32

K=12

N=42

42-32=10

10+2=12

Answer 2

ANSWER

$k < na < o < n$

Explanation:

across the period ionisation enthalpy increase and down the group decrease....

So according this O has more ionisation enthalpy but N has more because in N it has half field p orbital it maintains it stability hence energy increase so it has more IE than O

And O can loss one electron to become half field hence its energy is less

I hope this is help you...
