Question

If three isotopes have a mass and abundance of a small percentage of 97 amu, just over half of all abundance of 99 amu, and the remaining abundance of 100 amu, to what number would the average atomic mass be closest?

Answer 1

Answer:

no answer

Explanation:

Isotopes are atoms that have the same atomic number but different mass numbers due to a change in the number of neutrons. ... While the presence of isotopes affects the mass of an atom, it does not affect its chemical reactivity. Chemical behavior is governed by the number of electrons and the number of protons.
