Types of isotopes
Abundance of isotopes : total is 100
(the percentage/ ratio)
Isotopic mass
2
Q
Relative is a
A
Ratio hence there is no unit
3
Q
Explain the atomic mass of an element (ie cu) is the average isotopic mass
A
The atomic mass of an element is the average of its isotopic masses weighted according to their natural abundances and is determined by modern instruments such as mass spectrometer.
