Ch 2: Atoms: Tutoring Solution

About This Chapter

The Atoms chapter of this College-Level General Chemistry Tutoring Solution is a flexible and affordable path to learning about atoms. These simple and fun video lessons are each about five minutes long and they teach all of the information involving atoms required in a typical college-level general chemistry course.

How it works:

  • Begin your assignment or other chemistry work.
  • Identify the atoms 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 college-level general chemistry tutoring solution will benefit any student who is trying to learn about atoms and earn better grades. This resource can help students including those who:

  • Struggle with understanding atomic and mass numbers, average atomic mass, electron configurations in atomic energy levels or any other atoms 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 atoms 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 atoms 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 atoms on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning Objectives

  • Learn how to determine the atomic number and mass number of an atom.
  • Explore early atomic theory.

Atomic Number and Mass Number

1. 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

2. 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

3. 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

4. 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

5. 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.

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

6. 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

7. 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.

What is a Wave-Mechanical Model?

8. What is a Wave-Mechanical Model?

When scientists realized that electrons around the nucleus of an atom don't really behave like planets around the sun, they had to propose a new model. This lesson will discuss the wave-mechanical model of the structure of an atom.
