Atoms, Elements, and Molecules
ATOMS-the basic building blocks of everything you see around you, even things you don’t see!
ELEMENTS-the kinds of atoms we can have!
MOLECULES-when atoms join together, forming bonds!

These long polymer chains are These long polymer chains are formed by teeny tiny molecules formed by teeny tiny molecules called called monomersmonomers..
A single polymer molecule is made A single polymer molecule is made out of hundreds of thousands (or out of hundreds of thousands (or even millions!) of monomers!even millions!) of monomers!
