Group # 1-18
The alkali metals have only one electron in their outermost energy level. The alkali metals are the most reactive of all of the metals. Hydrogen is NOT a member.
This group has two electrons found in their outermost energy level. Alkaline Earth Metals are reactive.
Group 1 – Blue (true /dark blue) Group 2 – Green (true /dark green)
The transition elements are in the middle of the table. Can bond with many elements in a variety of shapes.
Part of the transition metals Moved to the bottom to keep the table from being too long All elements in the actinide series are radioactive & most are man made.
Groups 3-12 – Pink Lanthanide & Actinide Purple
Have three electrons in their outer energy level. Only one member of this family is a metalloid -- boron. The others are classified as metals.
These elements have four electrons in their outermost energy level. The element carbon is the basis of life. It is found in all living material.
Elements of this family have five electrons in their outermost energy level.
Each element has six electrons in its highest energy level. Oxygen is the most common element (by mass) in the earth's crust.
Group 13 – Light/lime green Group 14 – Gold (dark/orange yellow) Group 15 – Light brown Group 16 – Sky blue
This group is very reactive. The elements in this group are all one electron short of having a complete outer energy level.
Hydrogen belongs to a family of its own. Hydrogen is a reactive gas. Hydrogen was involved in the explosion of the Hindenberg. Hydrogen is promising as an alternative fuel source for automobiles
Group 17 – Orange Hydrogen – Light yellow
The noble gases do not react with other elements because their outer energy level is full. Meaning they are stable and happy!
Group 18 – Red
