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.

Three widely used definitions of atomic radius are: Van der Waals radius, ionic radius, and covalent radius.
the atomic number determines the tyoe of element an atom is.
the atomic number means the number of protons in an atom.
atoms of different elements have different numbers of protons and different atomic numbers so you can identify the element based on the atomic number
