What is Matter Made of Molecule- The smallest part of a substance that is made up of two or more atom is a molecule.

What is an atom

Elements 92 kinds of basic materials Periodic table Smallest piece is called an atom

What is a molecule

How Do Atoms Rearrange Ca Co 3 2H Cl = CO 2 + CaCl 2 +H 2 O (Copy the equation- Mrs McComas doesn’t know how to make special symbols for chemistry. (Arrows) I changed the size of the number to get the smaller number for the equation.) Calcuim carbonate and stomach acid Chalk- Calcuim Carbonate

Questions & Answers Question Is there anything smaller than an atom? Answer Yes, atoms are made of other smaller particles. Some of these particles are electrons, protons and neutrons. Scientists are still learning about even smaller particles. From fossweb.com
