Question

Atomic weight is A a weighted average of the masses of isotopes of an element based on abundance. B determined by weighting individual atoms. C an average weight of the isotopes of an element. D the number of protons and neutrons in a nucleus.

Answer 1

A a weighted average of the masses of isotopes of an element based on abundance.

Answer 2

Atomic weight, also known as relative atomic mass, refers to the calculation of the individual atomic masses of each isotope of an element, taking into account the proportions they make up of the overall population of that element. Essentially, different isotopes of the same element contribute to the atomic weight proportionately with their occurrence. This isn't an arbitrary system for calculating an 'average' weight though. The atomic masses of individual atoms aren't weighed. In addition, although protons and neutrons do contribute to the atomic weight quantitatively, just combining the number of protons and neutrons in a nucleus will provide the mass number of an element, rather than the average atomic weight which is a weighted average including the impact of various isotopes.
