The relative masses of each element can be found on the periodic table. For example, one atom of magnesium weighs
24.31 amu
(atomic mass units). However, one mole of magnesium weighs 24.31 g. (Moles were planned that way!)

Can deuterium be made?
Deuterium is produced
for industrial, scientific and military purposes
, by starting with ordinary water—a small fraction of which is naturally-occurring heavy water—and then separating out the heavy water by the Girdler sulfide process, distillation, or other methods.
Is deuterium in periodic table?
Re: Where is Deuterium on the periodic table?
It is not on the periodic table
! Deuterium is simply Hydrogen with one extra neutron (i.e., 1 proton, but the same atomic weight as He).
Which is heavier deuterium or tritium?
Deuterium
and tritium are isotopes of hydrogen, the most abundant element in the universe. Whereas all isotopes of hydrogen have one proton, deuterium also has one neutron and tritium has two neutrons, so their ion masses are heavier than protium, the isotope of hydrogen with no neutrons.
What is the name for 6H2O?
