Atomic radius always INCREASES as you move DOWN the periodic table (simply due to increasing number of electron shells). Atomic radius (sort of counter intuitively) DECREASES as you move ACROSS the Periodic Table. This is because increasing the number of protons (ie positive nuclear charge) causes electrons in the same energy level to "shrink" toward the nucleus.

Can you describe the general trend in atomic radius in group 2A?
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
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.
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
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.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
Can you describe the general trend in atomic radius in group 2A?
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
What is the Group trend Atomic radius?
Atomic radius increases down the group. This is because of the increase in number of shells.
What is the group trend in p-block element?
Atomic radius increases down the group
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 .
Do transition elements follow the same trend of atomic radius as the main group elements?
NO
What trend in atomic radius do you see as you go down a group on the periodic?
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
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 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.
What is the trend in atomic radius down a group explain?
the atomic radii increases down the group.
What is the trend in ionic radius from left to right within a period?
Atomic radius
What pattern or trend do you notice between atomic radius and electronegativity energy?
In general, they are opposing. Electronegativity increases going left to right in a period and up in a group. Atomic radius decreases going left to right in a period and up in a group.
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
