The Reactivity Series and Displacement

To determine whether an element will displace an element in a compound when it reacts with it, chemists use the Reactivity Series to see which element is more reactive

If the element in the compound is more reactive than the element it is reacting with, then it won't be displaced

If the element in the compound is less reactive than the element it is reacting with, then it will be displaced

Metals, Non-Metals and Metalloids

Metals

Physical Properties

ALL METALS
Shiny
Good conductors of heat and electricity
Malleable (can be bent without breaking)

MOST METALS
Solid (at room temperature)
High melting/boiling point
Hard & Strong
High Density (have a high volume to surface area ratio - are heavy for their size)
Ductile (can be drawn into wires)
Sonorous (ring when hit)

Chemical Properties
Easily lose electrons (to obtain a full outer shell)
Corrode easily (wear away)


Metalloids

Metalloids have some of the properties of metals and non-metals
  
Physical Properties
Solid
Malleable
Ductile
Conduct heat and electricity better than non-metals but not as well as metals
Can be either dull or shiny

Non-Metals

Physical Properties

ALL NON-METALS
Dull
Brittle (break easily)
Poor conductor of heat and electricity

MOST NON-METALS
Low density (have a low volume to surface area ratio - are light for their size)
Not malleable, ductile or sonorous

Non-metals have varying melting/boiling points. This is known by the fact that at room temperature, the non-metals can be found in different states. Eleven non-metals are gases, one non-metal is liquid (bromine) and the rest are solid.

Chemical Properties
Easily gain electrons (to obtain a full outer shell)
