The atomic radius of a chemical element is a measure of the size of its atom, usually the mean or typical distance from the center of the nucleus to the outermost isolated electron. The ionic radius is the radius of a monatomic ion of an element within an ionic crystal or half the distance between two bonded gas atoms Atomic radius of all the elements are mentioned in the chart below

Below mentioned radii are the van der waals radius in picometer (pm)).
Atomic radius is the distance of the outermost or valence electrons from the nucleus of an atom
Suppose one visualizes the atom to be a sphere where the nucleus lies at the center, and the outermost electrons lie at the boundary. Atomic radius, half the distance between the nuclei of identical neighbouring atoms in the solid form of an element An atom has no rigid spherical boundary, but it may be thought of as a tiny, dense positive nucleus surrounded by a diffuse negative cloud of electrons. Atomic radius is defined as the total distance between the center of the atom to the outermost orbit in which the electron is revolving
Atomic radius tells about the atomic size Since atoms are considered to be spherical, the size of an atom can be calculated by measuring its radius. Atomic radius refers to the atomic size, typically measured as the distance from the nucleus of an atom to the outermost shell of electrons In this article, we will study in detail what is atomic radius and its trend in the periodic table.
The atomic radius is the distance from the center of an atom to its outermost shell or the edge of its electron cloud
This fundamental property of atoms is closely related to their physical and chemical behavior, as it influences the interactions between atoms and their reactivity. What is an atomic radius If we imagine an atom as being like a solid sphere, then the radius would simply be the distance from the nucleus (located at the very centre of the sphere) to edge I’ve shown this on the diagram below:
While the atomic radius measures the size of a neutral atom, the ionic radius gauges the size of an electrically charged atom
