Ionic Radius | Trends of Ionic Radius in Periodic Table

This lecture is about ionic radius and trends of ionic radius in the periodic table.

Q: What is ionic radius?
.
Ans: The distance between the nucleus and outermost valence shell of an ion is called ionic radius.
For example, the atomic radius of sodium is 186 pm and the ionic radius of sodium is 95 pm.

You will also learn the following conceptual questions:
Q: What is atomic radii?
Q: Why the size of cations is smaller than its parent atom?
Q: Why the size of anion is greater than its parent atom?


To learn more about atomic radii, watch this lecture till the end.
