Question

33. Answer the following questions (8 Points) a. Arrange the following in increasing atomic size order Fr, Ar, Mg, Al b. Arrange the following in order of decreasing ionization energy N, C, Li, He c. Arrange the following in the order of increasing electron affinity Si, CI, Mg, Ar d. Arrange the following in the order of increasing electronegativity, Xe, C, Si, F

Answer 1

a) The increasing order of atomic size is,

Al < Mg < Ar < Fr

b) The decreasing order of ionization energy

He > N > C > Li

c) Increasing order of electron affinity

Ar < Mg < Si < Cl

d) order of increasing electronegativity

Si < C < Xe < F
