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.
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).
7 atoms. 3 hydrogen, one boron and 3 oxygen.

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.

7 atoms. 3 hydrogen, one boron and 3 oxygen.
Boron is an element and therefore contains boron atoms.
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.
there are 6
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.
