11. going from left to right in the periodic table, the atomic radius decreases. which of the following explains the atomic radii trend of elements across a period? the attraction decreases between the nucleus and the outer electrons. the attraction increases between the nucleus and the outer electrons. there is a decrease in the number of electron shells. there is an increase in the number of electron shells.

11. going from left to right in the periodic table, the atomic radius decreases. which of the following explains the atomic radii trend of elements across a period? the attraction decreases between the nucleus and the outer electrons. the attraction increases between the nucleus and the outer electrons. there is a decrease in the number of electron shells. there is an increase in the number of electron shells.

Answer

Brief Explanations:

As you move from left - right across a period in the periodic table, the number of protons in the nucleus increases (nuclear charge increases), while the number of electron shells remains the same. This leads to a stronger attraction between the nucleus and the outer - shell electrons, pulling the electrons closer to the nucleus and decreasing the atomic radius.

Answer:

The attraction increases between the nucleus and the outer electrons.
