NYSTCE Chemistry: The Periodic Table - Chapter Summary
Reviewing details about the periodic table is made possible when you go through the lessons in this chapter. They refresh your knowledge about:
- Elements and their properties
- Compounds and molecules
- Electron shell and ionization energy
- Valence electrons
- Main group elements vs. transition metals
These video lessons average about five to 10 minutes each, and you can watch them anytime on a computer or mobile device. A text transcript is available, too, with key terms and topics highlighted. If you need help, it's simple to contact the instructors via our dashboard feature.
NYSTCE Chemistry: The Periodic Table Chapter Objectives
The purpose of the NYSTCE Chemistry exam is to test your understanding of the science topics that New York State requires for certification as an educator. All of the topics in this chapter are part of the subarea 2 portion of the exam. This section makes up 16% of the entire test, and it contains multiple-choice questions. These questions will have you inspect different passages and actual periodic tables, and then you are to analyze them correctly. Prepare for these tasks by reviewing the lessons and then taking advantage of the quizzes to check your knowledge.
1. What Are Elements?
Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.
2. How Compounds and Molecules Are Built From Elements
Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.
3. 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.
4. The Electron Shell
You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?
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.
6. 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.
7. 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.
8. 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.
9. 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.
10. 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!
