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
