A
different numbers of neutrons causing different mass but NOT size
2
Q
what is relative atomic mass
A
it is the atomic mass found on the periodic table which is an average of all the naturally occurring isotopes of an element determined relative to the carbon 12 element.
3
Q

(and molar mass vs relative molar mass)
A
atomic mass = g/mol (g mol-1)
relative atomic mass does not have this unit
