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.

Boron has a larger atomic radius but a smaller atomic mass.
nitrogen- .70 angstroms (oxygen- .66 angstroms)
Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.
eka aluminum is gallium eka boron is scandium eka silicon is germanium
The atomic number of boron is 5, one less than the atomic number of the atom in the block to its immediate right.
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 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.
nitrogen- .70 angstroms (oxygen- .66 angstroms)

boron "Its Boron you Moron"- Mr. D
There are a few chemical properties of boron. The most important properties are atomic mass, density and iconic radius.
The metal is aluminum, atomic number 13, under boron in the III-A column of the Periodic Table.
Boron has the largest empirical atomic radius: 85 pm.
The covalent atomic radius of carbon is 70 pm; oxygen has 60 pm and lithium 140 pm.
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.
