Chemistry is the study of matter, and all matter is made up of atoms. We will learn about elements, atomic number and mass, isotopes, moles (chemistry moles, and compounds.


we will study about atoms and elements, tiny particles that make up the world around us. What are atoms, and what kind of properties do they have? How do we weigh and count atoms? We will answer those questions in this section...

The difference between atomic weight and atomic mass in chemistry, and how it compares to the physics definitions of weight and mass. 


How to calculate atomic weight from atomic mass and percent abundance of carbon isotopes.


Introduction to the idea of a mole as a number

Introduction to chemistry

  9:26 AM    

A major picture perspective of science and why it is captivating. How science identifies with math and different sciences.

what most people associate when they think of chemistry.
They think of scientists working on a bench with the different vials of different chemicals.
They might think of a mad scientist. Some of them boiling and changing colors. They might associate chemistry with chemical equations. Thinking about how different things will react together to form other things.They might think about models of the different molecules that can be depicted different ways.They might associate it with the periodic table of elements. And all of these things are a big part of chemistry.

Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.
