Place the following elements in order of decreasing atomic radius. Rn Cs Kr Kr>Rn>Cs Rn>Cs>Ks Kr>Cs>Rn Cs>Rn>Kr Cs>Kr>Rn Identify the species that has the smallest radius. cation anion neutral they are all the same size Which definition below represents the electron affinity? the amount of energy required to remove an electron the amount of energy needed to form a metal the amount of energy required to get to an excited state the amount of energy associated with the gaining of an electron the amount of energy required to from a crystal Place the following in order of increasing metallic character. Rb Cs K Na K

Explanation / Answer

(64) (c)

Kr (z=36) condensed electronic configuration is [Ar] 3d10 4s2 4p6

(65) (d) Cs > Rn > Cr

(66) (a) Cations have smaller radiu compared to their neutral and anionic forms

(67) (d) The amount of enegy associated with the gaining of an electron is known as electron affinity.

(68) (b) Na < K < Rb < Cs

(69) (d) with complete octet
