If you didn't turn your review in yet, send a picture of both sides to Mrs. Bowers!
Ok fine!
I absolutely will not.
What's the difference between an atom or a molecule?
An atom cannot be broken down during a chemical reaction, but a molecule could be (like in a decomposition reaction).
A molecule cannot be broken down during a nuclear reaction, but an atom could be.
A molecule shares electrons, but an atom transfers electrons.
A molecule is neutral but an atom has a charge.
What's the difference between a neutral atom and an ion? Select TWO.
A neutral atom has equal numbers of protons and neutrons.
A neutral atom has equal numbers of protons and electrons.
An ion has an imbalance of electrons and neutrons.
An ion is an atom that either gained or lost valence electrons.
