In a mass spectrum of an element, what does the height of each peak represent?
A.Relative abundance of that isotope
B.The charge of that isotope's ion
C.The atomic number of the element
D.The electron binding energy
Explanation
Core Concept
Each isotope ionizes and produces a peak at its mass-to-charge ratio; the detector counts ions, so peak height tracks how abundant the isotope is. Height is abundance, position is mass.
Correct Answer
ARelative abundance of that isotope
