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 happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
How does atomic radii increase or decrease in the table?
atomic radii increases from left to right in the periodic table from metal to non metal in the right
In the same period what have large atomic radii alkali metals or noble gases?
Noble gases have larger atomic radii than alkali metals in the same period.
What is the relationship between the atomic numbers and ionic radii of the elements in the group 3A?
I think that the ionic radii decrease

What is the difference between atomic radii and ionic radii?
atomci radii measures for an atom ionic radii measures for an ion
How can you find out the atomic radii?
Look for a reference chart in a book or online. Look for a Periodic Table of the Elements that has the atomic radii on it.
Define atomic radii?
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
How does atomic radii increase or decrease in the table?
atomic radii increases from left to right in the periodic table from metal to non metal in the right
What is vanadium's atomic radii?
vanadiums atomic weight is 50 AMUs
Why are the ionic radii of metallic elements smaller than the atomic radii of the same elements?
The ionic radii of metallic elements is smaller than its atomic radii, because the ion has less electrons. This gives it a smaller electron cloud and makes the atom smaller.
As you move up to down in a column of the periodic table elements have what?
It increases because as you move down a family / column in a periodic table, the amount of protons and electrons increase, creating more rings of electrons on the atom, therefore with more rings, the size of the element increases.
Atomic radii can be measured in?
Picometers, or ! trillionth of a meter.
What is the atomic radii of helium?
It is 31 pico meter.
In the same period what have large atomic radii alkali metals or noble gases?
Noble gases have larger atomic radii than alkali metals in the same period.
