Molecule Worksheets

For this moles, molecules and molecular mass worksheet, students solve 18 problems where they find the number of moles in a gas, they calculate the number of molecules in a sample of gas or they find the volume of gas in a sample given the number of moles at STP.

In this molecules, moles and molar masses worksheet, students find the atomic masses of 8 elements, they write the formulas for 6 diagrams of molecules and they find the molecular masses of 12 compounds. Students also find the fraction of atoms in compounds and determine the percent composition of each.

In this atoms, molecules and ions worksheet, students answer seven questions about topics related to the discovery of atomic structure, the law of conservation of mass, atomic theory and the law of multiple proportions. In addition they answer questions about bonding, atomic structure, mixtures, molecules, compounds and ions.

In this VSEPR theory worksheet, students draw the Lewis structures for 5 molecules, they build the molecule, sketch the structure, show the bond angles and name the molecule. They also answer a question about the VSEPR theory and what the letters represent.

In this VSEPR theory worksheet, students build models of molecules using styrofoam balls and pipe cleaners to represent lone pairs. Students complete a chart for 12 molecules with valence electrons, Lewis structures, bond angles, lone pairs, designation, and the shape of the molecule.

In this organic molecules activity, students solve thirteen problems about molecules in the lipid bilayer of a cell membrane and about acids and bases. They draw organic molecules and they complete chemical reactions with products.

This learning exercise is focused on the geometry of molecules. Students begin by drawing the Lewis Structures and then predict the shape of given molecules. Students will then use VSEPR to determine if their predictions were correct.

For each of the formulas given, pupils need to complete the chart with a name, drawing of the Lewis structure, and the drawing of a 3-dimensional ball and stick representation.  To complete understanding of molecules, your class should be able to build a model of the molecule using a ball and stick kit and then determine its shape category.

For this organic molecules worksheet, students solve four problems. They draw Lewis structures, they identify functional groups in a molecule, they draw resonance structures and they provide details of bonding within a molecule.

In this molecules worksheet, learners review the parts of an atom and use element mass to determine isotopes. Students give the group, period, and classification for the given elements. This worksheet has 6 short answer questions and 17 problems to solve.
