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...
Atomic weight and atomic mass
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.
How to use the atomic number and the mass number to represent different isotopes.
