Metallic Minerals:

* Appearance:

* Luster: Have a shiny, metallic luster like a piece of metal (gold, silver, copper).

* Color: Often have a consistent color, like silver, gold, or copper.

* Streak: Leave a dark streak on a streak plate (unglazed porcelain).

* Other Characteristics:

* Opaque: Light does not pass through them.

* Conductivity: Good conductors of heat and electricity.

* Malleability: Can be hammered or bent into different shapes.

* Ductility: Can be drawn into wires.

Non-Metallic Minerals:

* Appearance:

* Luster: Often have a dull, earthy, glassy, or pearly luster.

* Color: Can have a wide range of colors, often with variations within a single specimen.

* Streak: Often leave a light-colored streak on a streak plate.

* Other Characteristics:

* Translucent or Transparent: Light can pass through them, at least partially.

* Poor Conductivity: Poor conductors of heat and electricity.

* Brittle: Break easily.

Remember: There are exceptions to these general guidelines. Some minerals may have characteristics that fall in between the two categories.

Here are some helpful tools for identification:

* Streak Plate: Used to determine the color of a mineral's streak.

* Hardness Test: Uses a scratch test to determine the mineral's hardness on the Mohs Hardness Scale.

* Magnifying Glass: Helps you see details and textures.

If you're unsure about a mineral's classification, it's always best to consult a field guide or a geologist for assistance.
