Question

which of the following has the largest atomic radius among group 16 elements?
a s
b se
c po
d te

Explanation:

Step1: Recall atomic - radius trend in a group

Atomic radius increases down a group in the periodic table due to the addition of new electron - shells.

Step2: Identify the position of elements in Group 16

S (sulfur) is in the 3rd period, Se (selenium) is in the 4th period, Te (tellurium) is in the 5th period, and Po (polonium) is in the 6th period of Group 16.

Step3: Determine the element with the largest atomic radius

Since Po is the lowest - placed element among them in Group 16, it has the largest atomic radius.

Answer:

C. Po
