Boron dioxide would have formula BO2, with a total of three atoms, BUT this is NOT a possible compound.
B2O3, with 5 atoms, is called boron trioxide (or diboron trioxide, boron oxide, boron sesquioxide, boric oxide alternatively).

The elements are boron and oxygen. The number of atoms is 3.
There are 4 boron atoms in a molecule of borax, which has the chemical formula Na2B4O7·10H2O.
there are 5 electrons in boron atoms.
There is one boron atom in one molecule of BF3.

There is one boron atom in one molecule of BF3.
Boron atoms have 5 protons. You can derive this from the periodic table because the atomic number is the amount of protons the nucleus of an atom contains.
There are 4 boron atoms in a molecule of borax (Na2B4O7·10H2O).
That is because boron can not have a +4 valence, which would be needed to bind TWO atoms of oxygen (each with -2 valence). Boron simply lacks enough valence electron to do so: It has only three!!
5
7 atoms. 3 hydrogen, one boron and 3 oxygen.
There are 4.81 x 10^24 atoms in 4.0 moles of boron. This value is calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mol) by the number of moles of boron.
Boron is an element and therefore contains boron atoms.
