Periodic trends vary as we move across the periodic table. in general, as you move across a row (from left to right) in the periodic table a) ionic size increases. b) atomic radius decreases. c) nuclear charge decreases. d) ionization energy decreases.

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.

answer; how far out of place which the object finished relative to the starting location;

conservation of mass

mass before something happens = mass afterwards
