What is the atomic mass of an element listed in the periodic table?
The atomic mass of an element listed in the periodic table is the weighted average mass of all the isotopes of that element, taking into account their natural abundance. It is expressed in atomic mass units (amu) or grams per mole (g/mol).
Is hydrogen a natural or synthetic element?
No, since there is little or no free hydrogen on Earth. (plenty in the sun, and it is a natural resource there.) There is bound hydrogen on Earth (mostly water), but the energy required to extract it is greater than the energy it gives up in burning.
