It is amu or AMU.
Sulfur symbol is S, and its atomic mass is 32.

It is not, The mass number is (A). The symbol for atomic mass is (ma)
Atomic mass unit
If present, it is usually given in superscript from before the element's symbol.
atomic mass unit (short: a.m.u.), symbol 'u', equiv. with (in S.I. units) 1.66054*10-27kg
Symbol: He atomic #: 2 atomic mass: 4.002602
The element with the atomic mass of 118.69 is tin, symbol Sn.
i dont know its symbol it might be pu but the atomic # is 94 and the atomic mass is 244 i dont know its symbol it might be pu but the atomic # is 94 and the atomic mass is 244
Nitrogen has a gram atomic mass of 14.0067, an atomic number of 7, and the chemical symbol N.
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14
The 34 protons means that this is the element that has an atomic number of 34, which is selenium. The mass number for the isotope given is 67, which is the sum of the protons and neutrons. Mass number is not the same as atomic mass. Atomic mass is the total mass of the protons, neutrons, and electrons in an atom.
