Covalent Radius

Postby TiffanyL1G » Wed Oct 24, 2018 10:31 pm

Could someone explain why there isn't a trend for covalent radius?

Hello, I usually consider the same reasoning for any type of radius for atoms. The trends I have noticed is that as you go down a group the radius increases. As you go from right to left in a period the radius increases. Also, radius increases as you go from the top right corner to the bottom left. Hope this helps!

It's difficult to define a trend for covalent radius, since a covalent bond often involves two different elements, and not just one.

Are covalent radius and atomic radius equal?

Think of a covalent radius as a subdivision of atomic radii. The atomic radius of an element is defined as half the distance between the centers of neighboring atoms. The covalent radius of an element, specifically nonmetals and metalloids, is half the distance between the nuclei of atoms joined by a chemical bond.
