Who's it for?
This chapter of our middle school physical science tutoring solution will benefit any student who is trying to learn the periodic table and earn better grades. This resource can help students including those who:
- Struggle with understanding ionization energy, electronegativity, classification of substances by their physical properties, or any other periodic table 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 Periodic Table unit
- Cope with ADD or ADHD
- Want to get ahead in physical science
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning the periodic table 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 physical science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn the periodic table on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Understand the significance of valence electrons and energy levels.
- Learn about trends among groups and periods of the periodic table regarding atomic and ionic radii, ionization energy and electronegativity.
- Discuss trends in boiling point, trends in metallic character and the diagonal relationship among elements in the periodic table.
- Describe the differences between transition metals and main group elements.
- Use the physical properties of substances to classify them.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Transition Metals vs. Main Group Elements: Properties and Differences
Which is better: to be steadfast and consistent or to be a colorful chameleon? This lesson compares and contrasts the main group elements and the transition metals. Then make your own decision!
7. Classifying Substances by Their Physical Properties
After watching this video, you will be able to explain what physical properties are and use them to classify some common substances. A short quiz will follow.
