well... the whole process of getting it is quite simple:
first you multiply the mass of boron by 1 divided by the moloar mass which in this case it is 10
10.81 * (1/10) or 10.81/10 =1.081
second, you multiply the result by Avogadro's number or 6.02*1023
1.081 * (6.02*1023) = 6.5*1023
after this your finished. this is the process to finding the number of atoms to any element. hopes this helps!
4 boron atoms
1.00*10-7 moles of boron is how many grams is this
there are 5 electrons in 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.
4 atoms. Boron= 1 atom Flouride = 3 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 13 isotopes in the element boron. xD
Boron has five protons.The element boron has 5 protons.5

None, as pure Aluminium is an element which contains only atoms of Aluminium and nothing else.
