Electron Configurations in Atomic Energy Levels

1. Electron Configurations in Atomic Energy Levels

This lesson will explain what the electrons are doing inside the atom. Tune in to find out how we specify where they are located and how this location description will help us predict an element's properties.

Chemical Bonds I: Covalent

2. Chemical Bonds I: Covalent

Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.

Chemical Bonds II: Ionic

3. Chemical Bonds II: Ionic

Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.

Chemical Bonds III: Polar Covalent

4. Chemical Bonds III: Polar Covalent

Are you confused about how you can tell what kind of bond two atoms will form? This lesson will help you understand the difference between polar and nonpolar covalent bonds as well as how to predict how two atoms will interact.

Chemical Bonds IV: Hydrogen

5. Chemical Bonds IV: Hydrogen

This lesson defines and discusses important concepts behind hydrogen bonding. You'll learn when and why these bonds occur and which atoms are often involved.

Electronegativity: Definition & Trends

6. Electronegativity: Definition & Trends

The attraction of electrons is different depending on the element. This degree of attraction is measured by the element's electronegativity. In this lesson, we will discuss electronegativity, its trends in the periodic table, and bonding.

Electron Affinity: Definition, Trends & Equation

7. Electron Affinity: Definition, Trends & Equation

When an electron is added to an atom, a change in energy occurs. This change in energy is what we call the electron affinity. In this lesson, we will discuss electron affinity and its general trend in the periodic table.

Oxidation Number: Definition, Rules & Examples

8. Oxidation Number: Definition, Rules & Examples

Knowing the ion form of an atom is important when putting together atoms to form a compound. An oxidation number is assigned to an atom to know its ion form. In this lesson, we will go over the rules to assign oxidation numbers to atoms.

Bond Energy: Definition & Equation

9. Bond Energy: Definition & Equation

Chemical reactions involve the breaking and forming of chemical bonds. In this video lesson, we will learn about bond energy and how we can use it to measure the overall energy change of a chemical reaction.

Metallic Bonding: The Electron-Sea Model & Why Metals Are Good Electrical Conductors

10. 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.

Covalent Bonds: Predicting Bond Polarity and Ionic Character

11. Covalent Bonds: Predicting Bond Polarity and Ionic Character

Learn about covalent bonds and their two types: nonpolar covalent bonds and polar covalent bonds. Discover how to predict the type of bond that will form based on the periodic table. Learn what ionic character means and how to determine it.

Dipoles & Dipole Moments: Molecule Polarity

12. Dipoles & Dipole Moments: Molecule Polarity

Learn about dipoles and dipole moments in this lesson. Understand the relationship between dipole moments and molecule polarity, and learn how to determine if a molecule is polar or nonpolar.

Ions: Predicting Formation, Charge, and Formulas of Ions

13. 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.

Hydrogen Bonding, Dipole-Dipole & Ion-Dipole Forces: Strong Intermolecular Forces

14. 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.

London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces

15. 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.

Intramolecular Bonding and Identification of Organic and Inorganic Macromolecules

16. Intramolecular Bonding and Identification of Organic and Inorganic Macromolecules

Understand what a macromolecule is and be able to identify both organic and inorganic macromolecules. Organic molecules include proteins, lipids, carbohydrates and nucleic acids.
