Describe the physical properties of metals, non metals, and metalloids

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

the answer is b & c i believe : )

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
