Boron, B, with an atomic number of 5.
some physical properties of Boron are: its color is black, it is a solid and it is rough shape
There are three electrons in boron's outer energy level.
If boron-10 absorbs a neutron, it becomes boron-11. Boron-11 is stable and does not emit any particles. Please restate the question.

Boron has a larger atomic radius but a smaller atomic mass.
There are a few chemical properties of boron. The most important properties are atomic mass, density and iconic radius.
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.
Atomic radius increases down the group. So indium will have the largest atomic radius among the options given.
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.
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)
boron was named boron because of the properties it has
The answer is Boron :)
