Structure: AtomsNucleus: most of the mass

Protons –positive chargeNeutrons- neutral

Electron Cloud: most of the spaceElectrons- negative charge

MATTER: has mass and takesup space

Structure: MatterTypes of Matter

Mixtures: no set compositionHomogeneous mixHeterogeneous mix

Chemicals: set compositionpure elements: only 1 kind of atompure compounds- atoms arranged only 1 way (H2O)

Changes in MatterPhysical: no change in chemical composition (ex. change in state)Chemical: change in chemical composition (chemical reactions)

Chemical Reactions :Conservation of Masscombustion: rapid reaction with oxygen (burning)oxidation: slow reaction with oxygen (rusting)

electrolysis: separation of components through electricityTarnish: metals outer surface reaction with surrounding non metal

Structure: Matter CharacteristicsPhysical Characteristics:

property observed without changing the substance

physical state, color, texture, luster, conductivity, magnetic, flexibility, density, viscosity, malleable, surface tension,ductility, boiling point, melting point etc.

Chemical Characteristics:Properties that describe the ability of a substance to change into other substances

chemical reactions ( see previous slide)

Separation of chemicals uses different properties

LiquidGasPlasma

CONSERVATION OF MASS!!! The amount of the substance does not change

Structure: TemperatureLord Kelvin K – absolute temperature

scale(no negative values)

0 K is -273.15 °C and −459.67 °F

Temperature is measuring the amount of movement energy in a substance. The higher the temperature the more ‘movement energy’.
