From left to right across the Periodic Table, the atomic radius decreases. This trend occurs because a proton is added to an atom which each element, yet the electrons do not move significantly further away from the nucleus. In addition, the valence electrons do not result in much nuclear shielding when they are in obitals with the same principal quantum number. Thus, the protons more strongly attract the electrons, pulling them closer to the nucleus.
Yes it does. With each step to the right, another proton is added to the atomic nucleus, and another electron is added to the outer shell. The actual affect on atomic radius is somewhat complicated by the fact that the more protons there are, the more strongly the electrons will be attracted to the nucleus. But the electrons repel each other. The end result is that the more electrons there are, the larger the atomic radius will be.

Well, no, it does not. There is an exception here and there, but elements in a period gradually decrease in atomic radius as you go to the right.
No, atomic radius generally decreases from left to right across a period in the periodic table due to increasing nuclear charge, which attracts the electrons closer to the nucleus.
Atomic radius increases down a group because, with each period an additional energy level is added.

What trend in atomic radius do you see as you go down a group on the periodic?
As you go down a group on the periodic table, the atomic radius tends to increase. This is because each successive element has an additional energy level of electrons, leading to an increase in the size of the electron cloud around the nucleus.
Which element will have a larger atomic radius magnesium or cesium?
Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.
Does beryllium or barium have a bigger atomic radius?
Barium has a larger atomic radius than beryllium. This is because as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of energy levels. Barium is located lower in the periodic table than beryllium, leading to a larger atomic radius.
Which element has a larger atomic radius carbon or germanium?
Germanium has a larger atomic radius than carbon. This is because as you move down a group in the periodic table, the atomic radius tends to increase due to the addition of more electron shells. Germanium is located below carbon in the periodic table.
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 generally decreases as you move across a period from left to right due to increasing nuclear charge pulling electrons closer to the nucleus. In a group (down a column), the atomic radius tends to increase due to additional energy levels being added as you move down.
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.
Why do elements increase in size as you move down the periodic table?
Down the group, atomic radius increases. This is due to increase in number of shells.
When does the atomic radius of an atom increase?
the radius of an atom gets larger when moving left to right across the Periodic Table because elements gain protons and electrons- the increase in charge brings the atom radius in
What element have the largest radius?
Francium has the largest atomic radius of all the elements on the Periodic Table.
Which of these elements has the largest atomic radius. Aluminum potassium fluorine. Calcium?
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
What element have the smallest atomic radius?
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.
Which has the larger atomic radius silicon or bromine?
Silicon has a larger atomic radius than bromine. This is because as you move down a group on the periodic table, atomic radius tends to increase. Bromine is located further to the right on the periodic table and has a smaller atomic radius compared to silicon.
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 properties increase down the periodic table?
Atomic Mass
How does the atomic radius of argon compare to krypton?
The atomic radius of argon is smaller than the atomic radius of krypton. This is because as you move down a group on the periodic table, the atomic radius tends to increase due to the addition of extra electron shells. Argon is located above krypton in the periodic table, so it has a smaller atomic radius.
