Edmentum
<u>Answer: </u>The correct answer is Option B.
<u>Explanation:</u>
The given elements that is sodium and sulfur are the elements which belong to the same period that is third period.
As, the electrons are added up to the same shell across a period, the number of protons also increase and hence, they attract the electrons more effectively. This means that the effective nuclear charge also increases and the size of the sulfur thus shrink and hence, the size (atomic radius) of sodium is the largest amongst third period.
Therefore, the correct answer is Option B.
