Ch 5: Understanding Atomic Structure: Tutoring Solution

About This Chapter

The Understanding Atomic Structure chapter of this Chemistry Tutoring Solution is a flexible and affordable path to learning about atomic structure. These simple and fun video lessons are each about five minutes long and they teach all of the fundamentals of atomic structure required in a typical chemistry course.

How it works:

  • Begin your assignment or other chemistry work.
  • Identify the atomic structure concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our chemistry tutoring solution will benefit any student who is trying to learn about atomic structure and earn better grades. This resource can help students including those who:

  • Struggle with understanding early atomic theory, Avogadro's number, the Bohr model or any other atomic structure topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning science visually
  • Find themselves failing or close to failing their atomic structure unit
  • Cope with ADD or ADHD
  • Want to get ahead in chemistry
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about atomic structure simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live chemistry tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about atomic structure on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

The Atom

1. The Atom

Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?

Atomic Number and Mass Number

2. Atomic Number and Mass Number

Atoms are the basic building blocks of everything around you. In order to really understand how atoms combine to form molecules, it's necessary to be familiar with their structure. In this lesson, we'll dissect atoms so we can see just what really goes into those little building blocks of matter.

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

3. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.

Isotopes and Average Atomic Mass

4. Isotopes and Average Atomic Mass

When you drink a glass of water, you are actually drinking a combination of heavy water and light water. What's the difference? Is it harmful? This video will explain the difference between the two types of water and go into detail on the significance of the different isotopes of elements.

Avogadro's Number: Using the Mole to Count Atoms

5. Avogadro's Number: Using the Mole to Count Atoms

How do we move from the atomic world to the regular world? Because atoms are so tiny, how can we count and measure them? And what do chemists celebrate at 6:02 AM on October 23rd each year? In this lesson, you will be learning how Avogadro's number and the mole can answer these questions.

Electron Configurations in Atomic Energy Levels

6. 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.

Atomic Structures: Pauli Exclusion Principle, Aufbau Principle & Hund's Rule

7. Atomic Structures: Pauli Exclusion Principle, Aufbau Principle & Hund's Rule

This lesson discusses the three main rules that govern how electrons fit in the atomic structure by filling the shells, subshells, and orbitals. We will also review the basics of quantum numbers before learning these principles.

Diamagnetism & Paramagnetism: Definition & Explanation

8. Diamagnetism & Paramagnetism: Definition & Explanation

In this lesson, we learn more about electron configuration through the concepts of diamagnetism and paramagnetism. We will review electron structure in an atom, and define diamagnetism and paramagnetism.

Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

9. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin

Each electron inside of an atom has its own 'address' that consists of four quantum numbers that communicate a great deal of information about that electron. In this lesson, we will be defining each quantum number and explaining how to write a set of quantum numbers for a specific electron.

The Bohr Model and Atomic Spectra

10. The Bohr Model and Atomic Spectra

Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.

Bohr Model: Definition & Equation

11. Bohr Model: Definition & Equation

Explore the problem of the Saturnian atomic model, how the Bohr equation addresses this problem using the hydrogen atom, and what current theory has taken from the Bohr model to refine and improve on it.

Heisenberg Uncertainty Principle: Definition & Equation

12. Heisenberg Uncertainty Principle: Definition & Equation

The Heisenberg uncertainty principle is one of the core concepts in quantum mechanics. In this lesson, we define the uncertainty principle and learn more about its implications for physical science.

The de Broglie Hypothesis: Definition & Significance

13. The de Broglie Hypothesis: Definition & Significance

The de Broglie hypothesis states that particles of matter can behave as both waves and particles, just like light. In this lesson, we'll learn the basics of the de Broglie hypothesis and how it related to other theories released at the same time.

Pauli Exclusion Principle: Definition & Example

14. Pauli Exclusion Principle: Definition & Example

This lesson explains the Pauli Exclusion Principle, and its importance in the tiny world of electrons and atoms.
