Students distinguish atoms, molecules, elements, compounds and mixtures, classify everyday substances and particle descriptions, and read chemical formulas such as H₂O, CO₂ and C₆H₁₂O₆ to count the atoms of each element. They compare a mixture of iron and sulfur with the compound iron sulfide and explain why compounds have different properties from the elements that form them.

Element: one type of atom. Compound: different atoms chemically joined. Mixture: substances not chemically joined.
An atom is the smallest particle of an element. An element contains only one type of atom and is shown by a symbol, such as O for oxygen or Fe for iron.
A molecule is two or more atoms chemically joined. A compound contains two or more different elements chemically joined in a fixed ratio, such as water, H₂O.
A mixture contains two or more substances that are not chemically joined. Their amounts can vary, and they can be separated by physical methods such as filtering or evaporation.
A chemical formula shows which elements are in a substance and how many atoms of each. In NH₃ (ammonia), there is 1 nitrogen atom and 3 hydrogen atoms. A small number (subscript) applies to the symbol just before it. A large number in front (2H₂O) tells you how many molecules there are.
