Lesson Overview
About this worksheet
All matter is built from atoms. This worksheet teaches the parts of an atom – the nucleus, protons, neutrons, and electrons – and the difference between an element, a molecule, and a compound.
Section A on page 1 gives eight clues, and students write the term each one describes. The reference box names and defines each term, so students have what they need to match.
Section B on page 2 asks what an atom is, which three particles make it up and their charges, how a compound differs from an element, and for an example of a compound. Page 3 is a complete answer key with sample answers. The worksheet pairs well with the States of Matter and Physical and Chemical Changes worksheets.
