Moreover, what is atomic radius used for?
This Term Describes the size of an Atom—But It's Not Precise D. Atomic radius is a term used to describe the size of an atom. However, there is no standard definition for this value. The atomic radius may refer to the ionic radius, covalent radius, metallic radius, or van der Waals radius.
Also Know, what affects atomic radius? As the atomic number of an element increases, so does the size of its nucleus and the number of electrons around it. The bigger the atomic number, the larger the atom's radius. The growing size is due to the increasing number of filled electron shells as you move down the periodic table.
Keeping this in view, what is the atomic radius of an atom?
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.
Why does atomic radius decrease across a period?
Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.
