This channel (will) features a full high school chemistry course for free! It will be a perfect free home school chemistry curriculum, or as a study material for high school chemistry students. I'm a certified chemistry teacher, and have taught this exact chemistry curriculum to my own students for years.
I teach chemistry from my slides, offer examples and practice work for you to do, and even sometimes do chemistry labs in my kitchen! Feel free to follow along with my chemistry labs from your own kitchen. Just make sure to do it safely!

Average Atomic Mass Practice Problems
มุมมอง 217ปีที่แล้ว
In this video, learn how to calculate average atomic mass using data, how to determine the most abundant isotope, and using hypothetical data to determine the element or the most abundant element. If you need to review the lesson, check out this video: th-cam.com/video/JTJYgomIxog/w-d-xo.html
Bohr Electron Excitation, Ground State and Excited State in atoms, reading emission spectra
มุมมอง 916ปีที่แล้ว
Home School Chemistry Day 20 Unit 2: Atomic Theory Lesson 7: Electron Excitation This lesson teaches a little bit about how electrons are organized. It's an introduction to how electrons are organized and electron configuration. But truly, this will teach you how electrons can move around and jump from the ground state to the excited state. I'll also tell you why flame tests are cool, but not t...
How to Determine Number of Protons & Neutrons in Isotopes Practice Problems
มุมมอง 3.7Kปีที่แล้ว
In this video, I will go over how to determine the number of protons, neutrons and electrons in atoms of different isotopes of carbon and chlorine. The number of protons and electrons are equal to each other and are equal to the atomic number. The number of neutrons is determined from the mass number. Need more help?

Atomic Lewis Structures
มุมมอง 150ปีที่แล้ว
In this video there will be some practice on how to draw atomic Lewis structures, meaning these are atoms, not bonded to anything. If you need more information, you can watch the full lesson: th-cam.com/video/SIBv9FCGD8o/w-d-xo.html
Drawing Bohr Models Practice
มุมมอง 683ปีที่แล้ว
We'll practice drawing Bohr diagrams for some smaller atoms. This video does not teach the elements beyond atomic number 20 due to the d-shift. By default, it's a review of atomic structure: number of protons, number of neutrons, number of electrons and finally number of electron levels and the number of electrons in each level.

Dimensional Analysis Practice Problems
มุมมอง 256ปีที่แล้ว
We'll use dimensional analysis to find out the number of seconds in 15 years. Dimensional Analysis is taking a measurement and multiplying it by conversion factors in order to change the units. A conversion factor is two equivalent values (think 60 seconds and one minute) that have different units, but measure the same amount of time, mass length or quantity! Need more help? See how this can ap...
Scientific Notation Practice Problems
มุมมอง 457ปีที่แล้ว
We'll practice converting both large and small numbers into scientific notation and we will take scientific notation and convert it into standard notation. This is a critical skill for being successful in chemistry. Sometimes you'll need to take large numbers and get them into scientific notation in order to preserve the number of significant figures. Need more help? Counting Significant Figure...
