Question

Which of the following is ranked in order of largest to smallest atomic radius ?

a. Rb > V > As > C > O
b. Rb > V > Cl > As > O
c. O > Cl > As > V > Rb
d. Rb > As > V > O > Cl
e. V > Rb > O > Cl > As

Answer 1

The correct order from largest to smallest atomic radius is Rb > V > As > C > O, based on their positions in the periodic table. a. Rb > V > As > C > O

Step-by-step explanation:

The question is asking to rank the elements Rb, V, As, C, and O in order of decreasing atomic radius. Atomic radius tends to increase as you move down a group in the periodic table and decreases as you move across a period from left to right.

Hence, the largest atomic radius would be for the element lowest and furthest left on the periodic table (in this case, Rb), and the smallest would be for the element highest and furthest right (in this case, O). The correct order from largest to smallest atomic radius is thus: Rb > V > As > C > O.
