What is Chemistry?

What is Chemistry?

What is Chemistry?. The study of the composition, structure, and properties of matter, and the changes matter undergoes. What is Matter?. Anything that has mass and occupies space. How Can We Study Matter When There is So Much of It?. All of matter is made up of just a few “kinds” of matter.

HISTORY of the ATOM

HISTORY of the ATOM

HISTORY of the ATOM. Early Greeks, including Aristotle, believe that all matter composed of 4 elements: earth, water, air and fire. These elements were eternal and unchanging (like a stucco wall). Different substances were made up of the elements in different proportions,

Definite proportions and percent by mass

Definite proportions and percent by mass. Law of definite proportions. The Law of Definite Proportions states that a compound is always composed of the same elements in the same proportion by mass, no matter how large or small the sample.
