Question

The correct order of first ionization potential is
A) N > F > He > O > Mg
B) He > O > F > N > Mg
C) He > F > N > O > Mg
D) F > He > N > Mg > O​

Answer 1

Answer:

sorry I can not solve it

Answer 2

The correct order of first ionization potential is B) He > O > F > N > Mg

• it is defined  as the amount of energy required to remove the most loosely bound electron from an isolated gaseous atom
• it depends on the number of valence shell and nuclear charge
• it increases across the period
• it decrease down the group
• it usually turns a neutral gaseous atom into a cation.

hence the correct answer is B) He > O > F > N > Mg.
