VSEPR Theory: Valence Shell Electron Pair Repulsion Theory

10th - Higher Ed

In this atoms worksheet, students complete a graphic organizer by filling in the number of atoms, number of electron pairs, number of long pairs, bond angle, and molecular shape.

Drawing Lewis Structures

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded, and moving unshared pairs of electrons so that each atom has eight electrons.

VSEPR Theory: Predicting the 3-D Shapes of Molecules

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.

Atoms, Molecules, and Chemical Bonds

In this atoms worksheet, high schoolers review the parts of an atom, Bohr diagram, atomic number, mass number, and covalent bonds. This worksheet has 5 drawings and 26 fill in the blank questions.

Understanding Hybrid Orbitals

In this hybrid orbital worksheet, students read about hybridization in molecules. They are given six molecules and they draw Lewis structures, they identify the shape of the molecules, they identify the types of orbitals present and they indicate if there are pi bonds present.

Unit 2 ~ Atomic Structure

As an atomic structure reference and review tool, this handout fits the bill. The first page provides definitions and tables of orbitals, electrons, and energy levels. The second page is an opportunity to practice determining numbers of electrons, atomic mass, orbital notation, and numbers of energy levels. Answers for the 18 review questions are provided following the practice problems.

The Atom, Atomic Number, Mass Number, and Isotopes

Expose your chemistry learners to atomic theory. As they view this PowerPoint, they will learn about subatomic particles, atomic number, and mass number of atoms as well as how isotopes are structured. Throughout this neat and accurate presentation you will find learning-check slides that can be used to assess understanding.

History of the Atom

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse the periodic table of elements and discover electromagnetic forces. This is a classy and comprehensive compilation of chemistry slides that even includes a link to a 13-minute video. 

Atoms, Molecules and Ions

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes by teaching how to name molecular compounds, including acids and bases. An added plus to this slide show is the practice problems that are inserted throughout.

Ionic, Covalent, and Metallic Bonds

Sal introduces students to the ways that atoms "stick together" by bonding. Students see that the process of atomic bonding is what creates molecules. He outlines specific examples of atoms combining through covalent bonding, polar covalent bonding, and metallic bonding. Previous knowledge of how electrons are given away and taken by elements would come in handy when viewing this presentation for the first time.

Interactive Quiz 2

In this chemistry interactive quiz, students answer 15 multiple choice questions on chemical bonding, enthalpy and Lewis structures.

Lesson Planet is a great portal that has given me a lot of great ideas for topics for which I have less preparation, such as physical science.
