Element Groups and Their Properties

• Boron Group

• Carbon Group

• Pnictogens

• Chalcogens

• Halogens

• Noble Gases

Alkali Metals

• The word alkali is derived from the Arabic Word al-qali, which means ashes.

• Alkali metals are the most reactive of all metals and are thus found in nature as compounds.

Alkaline Earth Metals

• They form alkaline (basic) solutions and are commonly found in the Earth's crust.

• These materials are generally harder and less reactive than alkali metals.

Boron Group

• Moderately reactive elements.

• Boron is the only metalloid in the group; the rest are metals.

Carbon Group

• The elements in this group are not very reactive, but all react with oxygen upon heating.

Pnictogens

• The reactivity of the elements in this group varies.

• Nitrogen is unreactive, while phosphorous is highly reactive.

Chalcogens

• The group is consist of elements with varying metallic properties.

Halogens

• Highly reactive elements, especially with alkali metals.

• They readily combine metals to form salts.

Noble Gases

• They are rare gases on Earth.

• Also called, inert gases, these gases are the least chemically reactive among the elements; they rarely form compounds.
