Families of metals:

Alkali metals - Group 1 1 electron in their outer energy level. React with water to release hydrogen gas. The most reactive metals.

stored under oil

Alkaline earth metals - Group 2 2 electrons in their outer energy level.	"mag" wheels

Transition metals - Group 3 to 12 2 electrons in their outer energy level. Commonly have more than one oxidation number. Form compounds that are brightly colored.

The Precious Metals

Rare-earth metals - Two rows below the main body of the table 2 electrons in their outer energy level. Their primary oxidation number is +3. Within the rare-earth group, there are two sub-groups: Lanthanoid series - elements #57-71 Soft, malleable metals with a high luster and conductivity. Actinoid series - elements #89-103 All these metals are radioactive.

Families of nonmetals:

Boron family - Group 13 3 electrons in their outer energy level. Aluminum is the most abundant metal and the third most abundant element in the Earth's crust.	aluminum

Carbon family - Group 14 4 electrons in their outer energy level. Carbon's unique characteristic of bonding to itself is responsible for complex molecules composed of long chains of carbon atoms. Silicon is the second most abundant element in the Earth's crust.	diamond is pure carbon

Nitrogen family - Group 15 5 electrons in their outer energy level. Nitrogen is the most abundant element in the Earth's atmosphere.	phosphorus is a key ingredient

Oxygen family - Group 16 6 electrons in their outer energy level. Oxygen is the most abundant element in the Earth's crust. Oxygen supports combustion.	sulfur

Halogens - Group 17 7 electrons in their outer energy level. Halogens easily combine with metals to form salts. Most reactive of all nonmetals.	Iodine

Noble gases - Group 18 8 electrons in their outer energy level. Because of their electron arrangement Noble Gases are almost complete inactive, "inert". All members of the family are colorless gases. Argon is the most abundant Noble Gas, making up almost one percent of the atmosphere.

Day 3

What is the most active metal on the periodic table?

Metalloids:

Elements with properties of both metals and nonmetals.
Elements touching the metal-nonmetal line on the table.

Silicon and Germanium are two metalloids important in the manufacture of computer chips.

Their conducting characteristics all electric circuits to be "printed" in them.
