Group 1 Alkali Metals

Group 1 contains all metalsThey are VERY reactive. They are only found

combined with other elements since they are so reactive.

They have a low density, are soft, and are silver colored.

One Electron in outer shell

Potassium

Sodium

Group 2 Alkaline Earth Metals

Group 2 contains all metals

The are VERY reactive, but less reactive than group 1.

They have a low density, and are often mixed with other metals.

Two Electrons in outer shell

Magnesium

Group 3-12 Transition MetalsGroup 3-12 contains all metalsThey are less reactive than groups

1 and 2.

They are good conductors of thermal energy and heat.

The properties of transition metals varies among the different elements.

TitaniumMercury

Gold

Group 13 Boron Group

One Metalloid (semi-metal) and 4 metals

They are reactive, yet less reactive than groups 3-12

They are all Solid at room temperature.

They have 3 electrons in their outer shell.

Group 16 Oxygen Group

3 nonmetals, 2 metalloids (semi-metals)

Elements in the Oxygen group are reactive.

They are all solids at room temperature except for Oxygen which is a gas.

6 Electrons in their outer level

Sulfur

Group 17 Halogens

There are 4 non-metals and 1 semi-metal

They are Very reactive and often combine with elements from group 1.

Never found uncombined in nature.

7 Electrons in Outer Shell

Iodine

Bromine

Group 18 Inert Gases (Noble Gases)

Made completely of nonmetals.

All are in the gas state at room temperature.

Considered to be NOBLE because they are unreactive.

Outer Electron Shell is full. 8 Electrons
