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.

Resource Details


Ionic and Covalent Bonds

Ionic and covalent bonds are the focus of this chemistry activity, which provides students with eighteen key terms to use in a fill-in-the-blank activity. Additionally, students are prompted to write the number of atoms in four given elements, as well as decipher a diagram of carbon tetrachloride.

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, students 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.

Atomic Structure

In this atomic structure worksheet, students review concepts about the components of the atom through 9 short answer questions. Students fill in a table of elements with their subatomic particles, atomic number and mass number.

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.

Covalent Bonding and Molecular Structures

There are 66 objectives to be covered by upcoming chemists if they complete this two-chapter assignment. It encompasses all of the information needed to deal with covalent bonds and molecular geometry. Colorful diagrams display the molecular orbital structures. Charts are used to compare them. Practice problems and vocabulary definitions abound!

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.

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.

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.
