Practice problem
Why is knowing the mass of an atom not enough information to know the identity?
Mass only considers the number of neutrons, so we cannot tell what element something is.
Isotopes of different elements can have the same mass, so we also need to know the number of protons.
The mass of an atom changes over time, so it cannot be used to determine identity
Knowing the mass is enough information to determine identity
Type a concept, like “slope” or “photosynthesis”.
