Groups in the Periodic Table

Group 1: Alkali Metals Most reactive elements.

White, soft metals. Gives up electrons easily. One valence electron(Gives up Easily)

Group 2: Alkaline Earth Metals

Less reactive metals. Forms many ionic compounds. Ions: Charged Atoms. 2 valence eletrons.

Group 3-12: Transition Metals

Very dense and High Melting/Boiling point. Combine with oxygen to form oxides. Valence Number varies.

Group 13: Boron Family

Boron=metalloid. Aluminum and the rest=Metal. Three valence electrons

Group 14: Carbon Family

Fairly unreactive. Found free in nature. Form organic compounds. Carbon is “The Basis of Life”

Group 15: Nitrogen Family

Nitrogen=78% of earth's atmosphere. Form Covalent Bonds. Covalent: Sharing of electrons. Five valence electrons.

Group 16: Oxygen Family

Oxygen is the most abundant element in earth's crust! Very reactive with transition metals. Combined with many elements. Six valence electrons.

Group 17: Halogens

Easily Gain electrons. Combine with Alkali metals to form salts. Most reactive nonmetals. Seven valence electrons.

Group 18: Noble Gases

Inert elements. Very stable. All are found in small amounts in earth's atmosphere. Eight Valence electrons.

Lanthanide Series

Rare Earth Metals(57-71): Soft, malleable, high conductivity + luster.

Actinide Series

Rare Earth Metals (89-103): Synthetic, most are radioactive
