What is Matter?
-Matter is anything that takes up space (volume) and has mass. Matter
can be broken into different sections:
-Some elements are paired in twos. They are known as Diatomics.
e.g.: I2, H2, N2,
Br2, O2, Cl2,

are still considered elements and not compounds because they are still only one type of atom. A Compound must be two or more
different types of atoms.
