About This Chapter
AQA A-Level Chemistry: Bonding - Chapter Summary
The instructors for this chapter have compiled materials and created fun lessons perfect for helping you study for the AQA A-Level Chemistry test. After you review videos or full transcripts, you will have the knowledge to answer bonding questions that ask you to:
- Define the meaning of ionic bonds, and polar and nonpolar covalent bonds
- Describe covalent bonding and electron shells, and define metallic bonding
- Provide details about hydrogen bonding, dipole-dipole and ion-dipole forces
- Discuss London dispersion forces, states of matter and ions
- Share details about states of matter and chemical versus physical changes to matter
- Explain how molecules and compounds are built from elements
The lessons in this chapter are short, averaging about 10 minutes each. This helps you streamline your study process so that you always have time to work on your other school obligations. Timelines in the video lessons allow you to further streamline your preparations by offering a skip feature you can use to jump to key topics without watching videos in full. At any time, feel free to test your knowledge of bonding with short quizzes. A chapter exam is also available to reinforce concepts covered in the lessons.
1. Ionic Bonds: Definitions and Examples
Did you know that when atoms stick together to form molecules, they gain and lose electrons, making them negatively or positively charged? In this lesson, you will learn how cations and anions form one type of chemical bond called an ionic bond.
2. Polar and Nonpolar Covalent Bonds: Definitions and Examples
Did you know that some types of chemical bonds behave similarly to the way that children play with toys? In this lesson, you will learn about two types of bonds called polar and nonpolar covalent bonds.
3. Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule
Learn about the different electron shells of atoms as well as the octet rule for valence electrons and how that applies to covalent bonding. Discover the definition of covalent bonding and the relationships between atoms.
4. Metallic Bonding: The Electron-Sea Model & Why Metals Are Good Electrical Conductors
Learn why metallic bonding is called the electron sea model. Discover why metals bond the way they do and why they are shiny, malleable and conduct electricity well.
5. Hydrogen Bonding, Dipole-Dipole & Ion-Dipole Forces: Strong Intermolecular Forces
Learn about intermolecular vs. intramolecular forces. Learn the different intermolecular bonds (including hydrogen bonding and dipole-dipole and ion-dipole forces), their strengths, and their effects on properties, such as boiling and melting points, solubility, and evaporation.
6. London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces
Learn how London dispersion forces are created and what effect they have on properties such as boiling and melting points. Discover this weak intermolecular force and how it is one of the Van der Waals forces.
7. States of Matter: Solids, Liquids, Gases & Plasma
Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.
8. States of Matter and Chemical Versus Physical Changes to Matter
The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.
9. How Compounds and Molecules Are Built From Elements
Did you know that elements are somewhat like people and have different personalities? Some elements like to be left alone. Others prefer to hang out with friends. We'll discuss how elements build molecules and compounds and how these can be classified.
10. Ions: Predicting Formation, Charge, and Formulas of Ions
Learn how ions are formed using the octet rule. Use the periodic table to predict the charge an atom will have when it becomes an ion. Learn whether an ion is a cation or anion and how to write the formula depending on what charge the ion has.
