Question

write the formula of compound you will expect boron to form with oxygen

Answer 1

I thing BO2 compound is formed.

Answer 2

The correct answer is - B₂O₃

Boron is the only element in Group 13 of the periodic table that does not possess any metallic properties. In general, the oxides of nonmetals are acidic

The behavior of boron to air depends upon the crystallinity of the sample, temperature, particle size, and purity.

Boron does not react with air at room temperature. However, at higher temperatures, boron does burn in air to form boron (III) oxide, B₂O₃.

4B + 3O₂ (g) → 2B₂O₃ (s)

Boron trioxide or B₂O₃, which is the most common oxide form of boron, can also be obtained by heating boric acid.

2B(OH)₃ → B₂O₃+3H₂O
