What is an atom's nucleus made of?
protons plus the number of neutrons
both that atoms are mostly empty space and that atoms contain a nucleus
naturally occurring isotopes
numbers of neutrons
protons
Protons and neutrons
it is a weighted average, so common isotopes have a greater effect than uncommon ones

The atomic mass of an element is defined as the weighted average mass of that element's
protons plus the number of neutrons
both that atoms are mostly empty space and that atoms contain a nucleus
naturally occurring isotopes
numbers of neutrons
protons
Protons and neutrons
it is a weighted average, so common isotopes have a greater effect than uncommon ones
