Unformatted text preview: 1. As you go across the 3rd period from Na to Ar in the Periodic Table, the atomic radii (increase or decrease) and the ionization energies generally (increase or decrease), and these trends are primarily due to increasing (effective nuclear charge Z eff or shielding)? (1) increase, decrease, shielding (2) decrease, increase, shielding (3) increase, increase, Z eff (4) increase, decrease, Z eff (5) decrease, increase, Z eff 2. The following series for which the indicated atoms are correctly ordered by increasing atomic radius is (1) O < As < S < Se (2) O < S < As < Se (3) As < Se < S < O (4) Se < As < S < O (5) O < S < Se < As 3. Arrange the following in order of increasing size: Ar, K + , Cl- , S 2- , Ca 2+ (1) Ca 2+ < K + < Ar < Cl- < S 2- (2) Ar < K + < Cl- < S 2- < Ca 2+ (3) K + < Ar < Cl- < S 2- < Ca 2+ (4) Ar < K + < Cl- < Ca 2+ < S 2- (5) Ca 2+ < K + < Ar < S 2- < Cl- 4. Rank in the order of increasing ionic radius : Br- , Te 2- , I- smallest→largest (1) Br -1 < I -1 < Te 2- (2) Br...
