How does one calculate atomic radius

[MariahClark 2F]

Im not quite sure if we will be asked to calculate the atomic radius ever but I think its worth knowing how to get a generalization with a periodic trend. In general, the size of an atom will decrease when you go from left to right on the periodic table but will increase as you go down a certain group.

I do not think we will need to know how to exactly calculate atomic radii but instead just to be aware of the trends occurring on the periodic table in regard to it.

There's different approaches to finding the atomic radius that depend on the element's condition. If the element is a metal, its atomic radius is half the distance between the centers of neighboring atoms in a solid sample. If the element is a nonmetal or metalloid, we use half the distance between the nuclei of atoms joined by a chemical bond (also know as covalent radius). If the element is a noble gas, we use van der Waals radius. Section 2.8 in the textbook has helpful graphics!
