Ch 50: MTEL Middle School Math/Science: Atomic Structure

About This Chapter

Prepare for questions about atomic structure on the MTEL Middle School Mathematics/Science exam by viewing the video lessons in this chapter and taking the self-assessment quizzes.

MTEL Middle School Math/Science: Atomic Structure - Chapter Summary

The video lessons in this chapter provide an in-depth review of atomic structure and theory to help you prepare for chemistry questions on the MTEL Middle School Mathematics/Science exam. The lessons will cover the following topics:

  • Exactly what an atom is
  • Early atomic theory
  • Atomic numbers and structures
  • The creation of light
  • Isotopes and atomic mass
  • Avogadro's Number and using the mole
  • Electrons role in the atom
  • The four quantum numbers and how to write them

Walk through atomic structure with the instructors in these video lessons. If you would like some text-based learning, a transcript of the video is provided with each lesson. Take the self-assessment quizzes to see how well you can apply the information reviewed in each lesson.

MTEL Middle School Math/Science: Atomic Structure Objectives

The MTEL Middle School Mathematics/Science exam is a teacher certification assessment for the state of Massachusetts, and it evaluates your readiness to teach the subject in a classroom setting. This exam is broken down into 10 subareas (5 math related and 5 science related) and the lessons in this chapter help you prepare for the chemistry portion of the test, which accounts for 8% of the final score.

The exam is completed on a computer and is made up of 100 multiple-choice questions and 2 open-ended items. Each of the open-response questions should take about 20-30 minutes to complete.

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.

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

7. 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

8. 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.

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

9. 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.
