Physical Property
• A characteristic of a substance that can be observed without changing the substance into something else

• See page 22
Chemical Property
• A characteristic that is observed when a substance interacts with another substance.

Metals
• a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity (e.g., iron, gold, silver, copper, and aluminum, and alloys such as brass and steel).
Nonmetals
• Any of a number of elements, such as oxygen or sulfur, that lack the physical and chemical properties of metals.
Metalloids
• an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. They are electrical semiconductors.
