Properties of Matter

Density

Amount of matter in a given space or volume.

Formula: D= M/V

Units: g/cm3

Volume

Space an object occupies

MeniscusMeasures the volume of the liquidUnits: Liters (L) & milliliters (mL)

Properties of Matter

Weight

Measure of gravitational force exerted on an object

Varies depending on position on Earth

Units: newtons

Mass

Measures the amount of matter in an object

Always the same no matter where the position

Units: kilograms (kg), grams (g), milligrams (mg)

Properties of Matter

Boiling Point

Temperature at which liquid boils and turns to vapor

Melting Point

Temperature at which a solid melts and turns to liquid

Properties of Matter

SolubilityHow much of a material dissolves in a substance

AtomsBuilding blocks of Matter

Matter is made of atoms

Consists of Protons (+)

Electrons (-)

Neutrons (N)

Atomic StructureInside

Nucleus (Center of the atom)

Protons

Neutrons

Outside

Electrons

Electrons

TINY!!!

Very light particles

Negative charge (-)

Circle the nucleusOrbitals: 2,8,18,32,50,72

Protons

Larger and heavier than electrons

Positive Charge (+)

Located in the nucleus (center of the atom)

Neutrons

Large and Heavy like protons

No electrical charge

Located in the nucleus as well

Describing AtomsAtomic Number

# of protonsIn general, # of protons= # of electrons

Atomic Mass Number

# of protons AND # of neutrons

Elements

Consists of only ONE kind of atom

Cannot be broken down into a simpler type of matter
