Want this question answered?
Boron, Aluminum, Gallium, Indium, Thallium and Ununtrium all inhabit Group 13 on the chart, so they are quite similar to each other chemically.

Boron Family
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.
well, it depends on how many electrons are there in the last orbital P....it can be any element from Aluminum to Argon (look at the periodic table)
The periodic table is organized not only by atomic number, but also electron configuration. The electrons in aluminum are most similar to gallium and boron, which is why aluminum is put where it is. Also, zinc, gallium and indium are metals, so aluminum is with a couple of the other metals.
The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.
The elements immediately above and below aluminum in the same column of a wide form periodic table: boron and gallium. As is usual for relatively light elements, aluminum is more like the element below it, gallium, than the one above it: Aluminum and gallium are both metals, while boron is a nonmetal. In compounds with oxyanions, however, boron is similar to aluminum compounds with oxyanions.
The boron family, Group 13 on the periodic table, is sort of a collection of "odd ducks" in that boron is a metaloid and aluminum, gallium, indium and thallium are poor metals. All of these elements have 3 electrons in their outer electron or valence shell. The (poor) metals find a lot of use, particularly aluminum. Boron is useful in the chemical industry for inclusion in various materials.
The oxidation state of boron is either three electrons or one electron. Boron has an valence electron configuration of ns2np1.
No, but Al is part of the Boron family.

The electron configuration of boron is: [He]2s2.2p1.
eka aluminum is gallium eka boron is scandium eka silicon is germanium
Boron and carbon are not similar but both are nonmetals.
