All About Matter!

In class we learned a matter chart:

MATTER

- has mass & occupies space

MIXTURE
Homogeneous

- uniform throughout
- appears to have only 1 component but actually more than one component that's spread throughout the substance

• solution
• colloid (ex. milk)
• eg. sugar in coffee (unable to see the sugar)

Heterogeneous
- non-uniform, different properties do not blend together
-appears to have more than 1 component
- all the components are visibly seen

• suspension
• mechanical mixture
• eg. trail mix

PURE SUBSTANCES

- one set of properties 

- one type or particles
-classified as either element or a compound

Element 

- made of atoms

- matter in its simplest form

- cannot be decomposed

• metal (eg. copper)

• metalloids (eg. silicon)

• non-metals (eg. sulphur)

Compound

- made up of elements chemically combined (more than one atom)

- smallest particle is a molecule

• ionic - salt / base / acid
• covalent
• eg. water
