P9+-+Metals+in+Mixed+Groups

The periods that our elements are in are: 3, 4, 5, 6. The groups that our elements are in are: 12, 14, 15.
 * Mixed Metals **

Our elements are: Aluminum, Tin, Lead, Gallium, Indium, Thallium, and Bismuth. All of our elements are solids.

Three physical properties are:
 * · They are usually shiny, they have luster.
 * · Ductile, they are capable of being hammered out thin.
 * · Their melting points are:


 * ** Metal ** || ** Melting Point **
 * (degrees Celsius) ** ||
 * Aluminum || 659 ||
 * Lead || 327 ||
 * Tin || 232 ||
 * Gallium || 29.9 ||
 * Indium || 156.6 ||
 * Thallium || 304 ||
 * Bismuth || 271.4 ||

Three chemical properties are:

Three interesting facts are:
 * In moist air, aluminum can combine with oxygen to form oxide.
 *  Lead dissolves in water and most cold acids.
 *  Many metals undergo corrosion.

Two common uses for metals in mixed groups are:
 * Galvanization is the process in which iron sheets are dipped into molten zinc in order to prevent it from rusting.
 * Metals have the ability to be deformed without breaking.
 * In space if unprotected pieces of metal touch each other, they stick together permanently.
 * Artillery (ex. Bullets, cannons, guns, etc.)
 * Kitchen appliances
