Answer: Option (B) is the correct answer.
Explanation:
In the periodic table when we move from left to right across a period then there occurs a decrease in atomic radius of the elements.
This is because electrons are added into the same shell and therefore, force of attraction between the nucleus and valence electrons is increases which leads to shrinkage in size.
Hence, atomic radius of the elements decreases.
Thus, we can conclude that in general, as you move across a row (from left to right) in the periodic table atomic radius decreases.
