Property: characteristic of something

Property: characteristic of something

1. Chemical Property: a property that changes the chemical makeup of the substance

   • Reactivity: Ability to react with other elements
   • Flammability: Ability to catch on fire

2. Physical Property: a property that can be observed without changing the substance

   • state of matter: solid/liquid/gas
   • Color/shape: the color or shape observed.
   • density: how many atoms are in a certain amount of space
   • Malleability: ability to rolled into thin sheets. Gold is the most malleable element
   • Conductivity: The ability to let heat/electricity pass through
   • Melting point: the temperature at which it changes from solid to liquid
   • Boiling point: The temperature at which it changes from liquid to gas
   • Solubility: The ability to dissolve in a solvent
   • Luster: Shininess. Silver has luster
   • Brittleness/Hardness: ability to break apart
   • Magnetism: attraction/repulsion to magnet. Aluminum is magnetic
   • Ductility: Ability to be pulled into wires. Copper is used for wires
