What is the trend in atomic radii when moving from top to bottom?

As a general rule, when moving left to right on the periodic table the atomic radius decreases due to increasing electromagnetic attraction of the nucleus to the electrons.

∙ 11y agoAs you move from left to right across the Periodic Table of the elements, the number of electrons, protons and neutrons increases by one. Hence, Hydrogen, H, is atomic #1. Helium, He, is atomic number 2.
Hydrogen has 1 proton, 1 neutron and 1 electron. Helium has 2 of each.
The size of the Atom actually decreases when you move across a row due to the fact that there are more protons in the center of the atom (than electrons), which offset the negative charge, and pull the electrons closer to the center.
So to answer your question, the atomic radius decreases across the periodic table of the elements from left to right.
PS The size increases as you move down the column because there is more 'stuff' making up each atom as we move down every column.

∙ 14y agoAtomic radius generally decreases from left to right across the table. As one adds more positive charge to the nucleus the pull exerted on the electrons becomes greater and the electrons (on average) move closer to the nucleus.

What is the Atomic polarizability trend?
The Atomic polarizability increases top to bottom i.e down the group and it decreases left to right . This trend is the same as atomic radius .
What trend in atomic radii do periods 3 through 6 have in common in the periodic table?
Generally is a decrease of atomic radius along a period, from left to right.
Why do trend happen in atomic radius?
i dont know what you are really asking but i know that is it increases from top to bottom and from right to left hope this helps
What is trend in first ionization energies as one proceeds down the group 7A elements How this trends relates to the variation in atomic radii?
Ionization energies go down of course. This is because radii are becoming larger due to addition of electron levels. These farther from the nucleus electrons require less and less energy to liberate from the atom.
What best explains the observed trend in atomic radii going down periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
What trend can be observed among the atomic radii of main-group elements down a group?
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.
What trend do you note for the atomic radii of period 3?
The size of atom decreasing.
What explains the observed trend in the atomic radii going down the periodic table?
The more energy levels that are occupied by electrons, the larger the atomic radius.
What trend in atomic radius occurs down a group in the periodic table?
Atomic radii increases moving down a group in the Periodic Table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus.

The Atomic polarizability increases top to bottom i.e down the group and it decreases left to right . This trend is the same as atomic radius .
What trend in atomic radii do periods 3 through 6 have in common in the periodic table?
Generally is a decrease of atomic radius along a period, from left to right.
What is the trend in atomic radius down a group explain?
the atomic radii increases down the group.
What periodic trends exist for atomic radii?
As you move across a row on the periodic table, the atomic radii becomes smaller due to the attraction between positive protons and negative electrons. As you move down a column, the radii increase due to the addition of valance electrons.
Why does the change for the atomic radii of the elements for period 3 from sodium to argon look similar to period 2?
Because the trend is the same. Atomic radius decreases from left to right across a period.
Why does the change for the atomic radii of elements in period 3 from sodium to argon look similar to period 2?
Because the trend is the same. Atomic radius decreases from left to right across a period.
What trend in atomic radius occurs going down on the periodic table and why?
Atomic radii increases moving down a group in the Periodic Table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus.
What trend is oberserved among the atomic radii of main-group elements down a group. eplain this trend?
The trend of atomic radius increases down a group on the periodic table. This occurs because each successive element down a group has another energy level. As more electrons are added, more energy levels are needed to hold the electrons.
