Don't tell me there the same thing because according to a Chem ditto I'm doing there not. Also how do you find them on the Periodic Table. Thanks!

So what would the atomic mass and mass number be for Hydrogen?

Atomic mass is the average of several elements' masses ((the formula is AM = (% abundance)(mass1) + (% abundance)(mass2) +...))
Mass number is just the mass of one element.

Atomic Mass And Mass Number
2016-12-11 19:42:43 · answer #3 · answered by Anonymous · 0⤊ 0⤋
Mass number is the mass (in a.m.u., atomic mass units) of a particular isotope of an element, and it is always a whole number. Mass number is also the sum of protons and neutrons in a given isotope.
Atomic mass, on the other hand, is usually not an integer since it is an average of all of the naturally occurring isotopes.
Look at is this way. Let's say you are selected to be the mass standard for all humanity, and you are assigned a mass of 100 human mass units. But if you average ALL humans, it would be unlikely that the average would be exactly your mass. Let's say that the average of all humanity relative to you would be something like 102.4532 h.m.u. This would be analogous to the difference between mass number and atomic mass.

-- Atomic number is the proton number. The number of protons in the nucleus only. Thus, it is always the smaller of the two numbers. -- Mass number is the total number of nucleons in the nucleus (the number of protons + neutrons). This will be the bigger of the two numbers always. -- Relative atomic mass you can consider to be the same as mass number. It is defined as "the weighted average mass of an element, relative to 1/12th the mass of an atom of carbon-12, taking into account naturally occurring isotopes". However, all mass numbers are worked out relative to carbon, so you can consider mass number and relative atomic mass the same thing. I got A* in my GCSE Chemistry and am hoping for an A in my AS.
