Ch 3: MTLE Chemistry: Atomic Structure

About This Chapter

Atomic Structure is a chapter in our MTLE Chemistry preparation course and study guide. With our short video lessons and self-assessment quizzes you'll be able review the atomic structure topics you need to be successful on your MTLE Chemistry test.

MTLE Chemistry: Atomic Structure - Chapter Summary

Our Atomic Structure chapter covers the basic of the atom and gradually introduces more in depth and complicated atomic concepts to give a complete overview of their structure and role to chemistry. This chapter will help you prepare for the MTLE Chemistry exam through lessons on:

  • Definition of an atom and early atomic theory
  • Electron configurations
  • The atomic spectra
  • Valence electrons
  • The periodic table
  • Atomic and ionic radii
  • Ionization energy and electronegativity
  • Diagonal relationships

By reviewing the structure of an atom, you'll be able to answer atomic structure-related questions on your exam with confidence. After you watch the engaging video lessons, take the corresponding self-assessment quizzes to test your understanding and make sure you'll have no problem succeeding on your MTLE Chemistry exam.

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?

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.

Electron Configurations in Atomic Energy Levels

3. 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.

The Bohr Model and Atomic Spectra

4. 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.

Valence Electrons and Energy Levels of Atoms of Elements

5. Valence Electrons and Energy Levels of Atoms of Elements

The periodic table contains a wealth of information. This lesson will explain how to use it to quickly determine the most useful information about the most important electrons. We will be focusing our discussion on valence electrons and energy levels.

The Periodic Table: Properties of Groups and Periods

6. The Periodic Table: Properties of Groups and Periods

How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.

Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

7. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

Atoms are VERY tiny. How do we measure their size? This lesson will explain how the size of an atom is measured and teach you how to predict the relative size of an atom based on where it is located on the periodic table.

Ionization Energy: Trends Among Groups and Periods of the Periodic Table

8. Ionization Energy: Trends Among Groups and Periods of the Periodic Table

Do you know someone who has undergone radiation as a form of cancer treatment? Have you ever thought about why X-rays have health risks? Watch the video to find out what these types of radiation are really doing to atoms, define ionization energy and identify ionization trends on the periodic table.

Electronegativity: Trends Among Groups and Periods of the Periodic Table

9. Electronegativity: Trends Among Groups and Periods of the Periodic Table

How is fluorine like a child that doesn't share his or her toys? Find out in this video on electronegativity where we will discuss group and periodic trends among the elements.

The Diagonal Relationship, Metallic Character, and Boiling Point

10. The Diagonal Relationship, Metallic Character, and Boiling Point

What may have once seemed like a bunch of random squares with letters in them is now shaping up to be one very organized chemistry reference. In this lesson you will discover three other trends that are found on the periodic table: the diagonal relationship, trends in metallic character, and trends in boiling point.
