Why does the radius of an atom decrease as you move from left to right across the periodic table within the same energy level?

That's how Mendeleev first assorted it. There's no other answer I could think of anything else.

WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
Does the first ionization energy increase or decrease from top to bottom in periodic table for the alkali metal family?
It decreases as the atom radius gets larger, so it decreases from top to bottom.

What happens to the atomic radius when you go from left to right on the periodic table of elements?
The atomic radius decrease, with several exceptions in periods 6 and 5.
How does the atomic radius change from the left to the right horizontal row in the periodic table?
from left to right the atomic radius decreases as the electrons that get added are added in the same shell as they are in the same period. the shielding effect remains constant but the proton number increases which inturn increases the effective nuclear pull on the electrons bringing the electrons closer to the nuclei hence decreasing the radius of the atom
How does the atomic radius increase or decrease horizontally on the periodic table?
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
Does the atomic radius decrease as you move up a group and across a period from left to right on the periodic table?
the atomic radius decreses from left to right in periodic table due to increase in the number of succesive element the electrons of the outermost shell are more attracted towards nucleus and the atomic radius or atomic size decreases.
How does atomic radius increase or decrease horizontally or vertically across the periodic table?
Increases vertically as you add new shells, decreases horizontally because you have more protons in the nucleus
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
Which atom has larger atomic radius Rb or Xe?
Rb is larger with a radius of 248 pm while Xe has one of 130 pm. It follows the trend that radii decrease as you move right across the periodic table.
How does the atomic raduis change across a period of the periodic table?
Atomic radius usually decreases from left to right across a period of the periodic table.
How does ionic radius change as you move down and across the periodic table?
Ionic radius (or radii) increases as you move down a group and across a period.
What periodic trend does the atomic radius follow?
The atomic radius gets larger toward the bottom left of the Periodic Table. In general, the radius gets smaller as you go from left to right across the same period and the radius gets larger as you go from top to bottom down the same group.
