Arrange these elements according to first ionization energy.

Question

highest to lowest ionization energy

Li

N

Be

C

B

F

O

Ne

Answer 1

IE increases going left to right and bottom to top in the periodic table. You should be able to arrange these according to that directive. Give it a try.

Answer 2

Hi Ariel,

See the link for periodic table for reference, https://i.pinimg.com/originals/d3/76/ae/d376ae821587e5d41e58245d172bfe29.png. As elements are listed to the right ionization energy increases and the further down it decreases. So these elements in highest to lowest ionization energy is: Ne, F, O, N, C, B, Be, Li.
