If you have a circle by itself, that's an atom. If you have two or more circles stuck together, that's a molecule. If a molecule has different kinds
of circles, that's a compound. If the circles are the same, it's an element.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.
