QUESTION
Technetium-99m the isotope notation is 98 TC 43. Is the atomic weight 98 amu?
The isotope notation for technetium-99m is ##""_43^(99"m")"Tc"##, and its atomic mass is 98.906 u or approximately 99 u.
The amu is equal to the number of protons plus the number of neutrons (mass number) because 1 proton = 1 amu and 1 neutron = 1 amu.
