Explain how our use of energy affects the environment. Describe what we do to get and turn the natural resource into energy, and tell about how it affects our environment. (Two answers). please answer

Metals-•Lustrous (shiny)

•Good conductors of heat and electricity.

•High melting point.

•High density (heavy for their size)

•Malleable (can be hammered)

•Ductile (can be drawn into wires)

•Usually solid at room temperature (an exception is mercury)

•Opaque as a thin sheet (can't see through metals)

Non-metal-•High ionization energies.

•High electronegativities.

•Poor thermal conductors.

•Poor electrical conductors.

•Brittle solids—not malleable or ductile.

•Little or no metallic luster.

•Gain electrons easily.

•Dull, not metallic-shiny, although they may be colorful.

Metalloid-Are generally solids

Can be shiny or dull (luster)May or may not be drawn into wire (ductile)May or may not be hammered flat (malleable)May or may not be brittleConduct heat and electricity better than nonmetals, but not as well as metals Tend to make good semiconductorsHave boiling points that are widely variedHave melting points that are widely variedHave densities that are widely varied
