Question

a. Write the following in order of increasing atomic radius: C, Ge, Si b. Write the following in order of increasing atomic radius: Al, B, Mg c. Write the following in order of increasingly negative electron affinity: Ar, Cl, K d. Write the following in order of increasing first ionization energy: C, Ge, Si e. Write the following in order of increasing first ionization energy: Al, Be, Mg

Answer 1

a ) increasing atomic radius : C < Si < Ge

b) increasing order : B < Al < Mg

c) increasing electron affinity : Ar < K < Cl

d) increasing first ionization energy : Ge < Si < C

e) increasing first ionization energy : Al < Mg < Be

explanation:

1) atomic radius increases in the group from top to bottom . and atomic radius decreases in the period from left to right

2) ionization energy increases in the period and and decreases in the group

3) electron affinity increases in the period and decreases in the group
