Boron, B, with an atomic number of 5.
The other word for atomic radius includes the Van der Waals radius, ionic radius, and covalent radius. The atomic radius refers to half the distance between the nuclei of identical neighboring atoms in the solid form of an element.
The covalent atomic radius of argon is 106 +/- 1o pm (pm is the acronym of the picometer).
The atomic radius is 216 pm.
Boron has a larger atomic radius but a smaller atomic mass.

Atomic radius increases down the group. So indium will have the largest atomic radius among the options given.
Aluminium and boron are in the same group, with aluminium below boron. Down the group, the energy level (or shell) increases. So aluminium will have larger atomic radius.
There are a few chemical properties of boron. The most important properties are atomic mass, density and iconic radius.
Aluminum has a larger radius than Boron because there are more electron filled 'orbitals' around its nucleus. Atomic radius increases down a group for that reason.
Boron has the largest empirical atomic radius: 85 pm.
nitrogen- .70 angstroms (oxygen- .66 angstroms)
what is the boron number in an atomic number/
They are all poor metals (except for boron, which is a metalloid). The reactivity decreases as you move down the group. The atomic radius increases as you go down the group.
Boron is a non meta element. Atomic number of it is 5.
