Interpretation:
The element from Magnesium, Silicon, Sulfur and Sodium having largest and the smallest atomic radius needs to be determined.
Concept introduction:
The atomic radius of a particular element is the measure of the atoms size. It can also be defined as the distance between the nucleus of the element to its boundary.
Answer to Problem 16PP
Na has the largest atomic radius and Sulfur has the smallest atomic radius.
Explanation of Solution
On moving from left to right in a period, the atomic radius decreases. The decrease in atomic radius is due to the fact that on moving from left to right, addition of valence electron on the same energy level takes place. Due to increase in
Therefore, Na has the highest atomic radius and Sulfur has the lowest.
On moving from left to right on a period, the atomic radius decreases. Therefore, Na has the highest atomic radius and Sulfur has the lowest.
