An element that is typically a hard, shiny solid, is malleable, and is a good conductor of heat and electricity
Metal
An element that is usually a gas or brittle solid at room temperature, is not malleable or ductile, is a poor conductor of heat and electricity, and is typically not shiny
Non-metal
An element that shares some properties of metals and some of non-metals
Metalloid
Those characteristics that can be observed without changing the identity of the substance such as size, shape, luster, conductivity, malleability, and magnetic attraction
Physical Property
Those characteristics that can be observed when a chemical reaction changes the identity of the substance, such as potential to rust, corrode, or combust
Chemical Property
A property that describes if heat or electrical charges pass through the material easily
Conductivity
The way the surface of a mineral reflects light; either metallic or non-metallic such as silky, dull, glassy, or resinous
Luster
A property that describes the ability of the material to be rolled or hammered into thin sheets
Malleability
A property that describes if the material is magnetic
Magnetism
A property that describes if the material has the ability to be pulled into thin wire without breaking
Ductility
Red oxides, formed by the reaction of iron and oxygen in the presence of water or air moisture
Rust
The result of a chemical reaction between a metal and its surroundings during which the metal is oxidized.
Corrode
The process of burning. A chemical change, especially oxidation, accompanied by the production of heat and light.
Combust
The amount of matter in a given space or volume, a relationship between mass and volume
Density
Likely to break, snap, or crack when subjected to pressure
Brittle
