what you are asking is why cobalt is more dense than boron. You will have to ask a higher power than I. But I will do what I can. atoms are weighed in AMU Atomic Mass units. Atoms are measured in angstroms. so an atomic density is the relation of angstroms the atom fills(volume)to how heavy it is(mass). Oh, and the mole is a very large number of atoms or molecules so that these really small weights and sizes become tangeable a.k.a. cubic inches, ounces, pound, cubic yards. Now why is there a difference in density of these substances... well they have more or less protons, neutrons, and electrons. Not to mention different arrangement of the electrons causes a different size. I hope that helped.

What is the atomic weight of bromine?
The atomic mass of Boron (B) is 11 but to be more accurate, the atomic mass is 10.81.
How many atoms of cobalt would there be in a 2.2-gram sample of cobalt?
Cobalt is an element. If you know the mass of the cobalt in question, then you can divided by the atomic mass (58.93 g/mole) and find the number of moles. Then multiply by 6.023 x 10^23 (atoms/mole) to find the number of atoms.
Is boron-10 or boron-11 more abundant?
Boron -11
What has more protons potassium or cobalt?
Cobalt has more protons
Which metal is more reactive titanium or cobalt?
Titanium is more chemically reactive than cobalt.
What will weigh more a mole of Na or a mole of S?
A mole of S (32 g) weighs more than a mole of Sodium Na (23 g)
Does iron weigh the same as iron oxide?
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
What is the atomic of cobalt?
The atomic number of Cobalt (Co) is 27. The atomic weight of Co is 58.9332 grams per mole. See the Web Links to the left of this answer for a periodic table with more information about this element!
Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O

Which weigh more water or ice?
It depends how much water and how much ice you hae. if you have 1 ice cube and 6 cups of water, the water will weigh more. But, if you have 10 ice cubes and 1/4 cup of water the ice will weigh more.
