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

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 4.81 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.
To find the number of molecules of Boron in 1.67 x 10²⁴ B atoms, we need to consider that Boron typically exists as individual atoms rather than molecules. Therefore, 1.67 x 10²⁴ Boron atoms corresponds to 1.67 x 10²⁴ molecules of Boron since each molecule in this case is a single atom. Thus, there are 1.67 x 10²⁴ molecules of Boron in that quantity of atoms.
Boron is an element and therefore contains boron atoms.
This cannot be possible. Atoms cannot be divided or separated, meaning there cannot be a part of an atom. Either you have 6 atoms or 7 atoms, etc. You can't however, have 6.5 atoms or 9.63 atoms. When expressing a number of atoms that has a decimal, usually it will be due to scientific notation, which requires it.
