This worksheet will serve as a practice to help students distinguish one element from another in a variety of chemical formulas. Also, this practice will also help students to count the atoms in a chemical formula AND whether it is a single molecule of a compound or multiple molecules.

NOTE: This is an ADVANCED practice, as compared to my regular Counting Atoms worksheets, in that all of the chemical formulas in this practice include polyatomic ions (chemical formulas involving parentheses).

Online Tutorials can be accessed from the worksheet through the QR Codes! Students must use a QR Code Scanning App for this opportunity.

All formulas are true formulas of real chemicals and were not just elements that were thrown together at random. From medicines to pesticides to food additives... have your students look them up if they're interested!

This is just ONE of FIVE! Get the others! Or buy the PACK for 10% off!

to see state-specific standards (only available in the US).
Develop models to describe the atomic composition of simple molecules and extended structures. Emphasis is on developing models of molecules that vary in complexity. Examples of simple molecules could include ammonia and methanol. Examples of extended structures could include sodium chloride or diamonds. Examples of molecular-level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms. Assessment does not include valence electrons and bonding energy, discussing the ionic nature of subunits of complex structures, or a complete depiction of all individual atoms in a complex molecule or extended structure.
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. Emphasis is on using mathematical ideas to communicate the proportional relationships between masses of atoms in the reactants and the products, and the translation of these relationships to the macroscopic scale using the mole as the conversion from the atomic to the macroscopic scale. Emphasis is on assessing students’ use of mathematical thinking and not on memorization and rote application of problem-solving techniques. Assessment does not include complex chemical reactions.
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium. Emphasis is on the application of Le Chatelier's Principle and on refining designs of chemical reaction systems, including descriptions of the connection between changes made at the macroscopic level and what happens at the molecular level. Examples of designs could include different ways to increase product formation including adding reactants or removing products. Assessment is limited to specifying the change in only one variable at a time. Assessment does not include calculating equilibrium constants and concentrations.
