Question

Arrange the elememts of second and third period in increasing order of ionization energy

Answer 1

Answer:

2nd period:

li,Be, B, C, N, O, F,Ne

incresing order means from lowest to highest

ionization energy is the enefy required to remove an electron

as we move across a period nuclear pull increase and we require greater energy to remove e

3rd period (increasing order)

Na, Mg,Al, Si,P ,S,Cl ,Ar
