Atomic mass is equal to the number of protons AND neutrons in the nucleus of an atom. Some elements have atoms with the same atomic number but which vary

mass spectrometry, variations in the amino acid sequence can be monitored. to define the overall atomic composition for the group of amino acids spanning a O-glycosites with high accuracy and confidence, and reveal up to 8-fold more

1. Explaining and how to calculate the relative atomic mass RAM or A r of an element (a) Introduction - defining relative atomic mass - carbon-12 scale. Every atom has its own unique relative atomic mass (RAM) based on a standard comparison or relative scale e.g. it has been based on hydrogen H = 1 amu and oxygen O = 16 amu in the past (amu = relative atomic mass unit).
