Here is an image of Periodic table with atomic radius values.
You can also download the HD image of the above Periodic table with atomic size, later from this article. (It’s Free)
Plus I have also mentioned the Atomic radius chart for elements in this article. (You can download this too)
But before that…
I have few questions for you.
- Do you really know what exactly is the atomic radius?
- What is that picometer (pm) written on the Periodic table?
- Which is the smallest atom in Periodic table?
- Which is the largest atom in Periodic table?
I’ll clear all these doubts,
Now let me finish few concepts very quickly.
What exactly is the Atomic radius in Periodic table?
In simple words, the distance from the center of the nucleus to the outermost orbit is known as atomic radius.
Or
The atomic radius is the half of the diameter of the atom.
How is atomic radius measured?
Atomic radius is measured by measuring the distance between the two adjacent atoms, and then dividing that distance by 2, we get the atomic radius.
Above image clearly shows you how the atomic radius is measured.
As you can see that the distance between two adjacent Hydrogen atoms is measured and then its half value will give you the atomic radius of that Atom.
Atomic radius is measured in…?
Picometers (pm).
Generally, the atomic radius is measured in picometers (pm).
1 pm = 10-12 m
1 picometer is equal to 10-12 meters.
Very small, isn’t it?
Yes, the atoms are very small in size. You can imagine the relative atomic size in Periodic table from the below image.
Must see: Atomic size trend in Periodic table (where you will come to know why and how the size of atoms changes across a period and along a group)
Now let’s see the atomic radius chart for elements of Periodic table.
