Do you guys know what matter is??
(you say: NO, what is it??)
Matter is anything that has mass and volume a.k.a everything around us
MATTER can be broken down into 2 categories:

PURE SUBSTANCE: only one set and kind of properties
MIXTURES: more than one set of property and substance
physically combined
These categories can be broken down further.

ELEMENTS: simplest form (cannot be decomposed) and made up of atoms
ie. metals, metalloids, non-metal
COMPOUNDS: made up of elements
chemically combined
smallest particle (molecule)
ie. ionic, covalent
MIXTURES can be broken down to 2 more categories.
HOMOGENEOUS MIXTURES:
uniform throughout

ie. solution
HETEROGENEOUS MIXTURES:
not uniform

ie. water and oil, salad dressing
can be broken down further to : SUSPENSION, MECHANICAL MIXTURE
