2. What are Alkaline Earth Metals?
Alkaline earth metals consist of any of the six elements, Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium
Alkaline earth metals are found in the crust of the earth, usually in rock structures
They have high boiling and melting points

3. Characteristics Alkaline earth metals are silver and white in color
They are soft and light metals which let them become malleable
The density is low in these metals

6. Unique features Alkaline Earth metals are not found freely in nature
They are distributed in rock structures
They have two electrons in their outer shell
The radium is formed by the decay of uranium
The radium is radioactive, and dangerous to touch
Magnesium and Calcium is very important to animal life
Calcium builds strong bones and regulates the body's temperature

7. Insoluble- Impossible to dissolve
All of the alkaline earth metals are shimmery and silver
They are are all flammable
They are insoluble in water
They have only two electrons in their outermost layer
Similarities
Insoluble- Impossible to dissolve

8. What are they used for ?
The six elements are used to make batteries, flashbulbs, fireworks, fertilizers, and different kinds of metal alloys
These metals are most useful when used in compounds
More Examples of what they’re used for:
Flares
Airplanes
Rockets
Missiles

9. Interesting Facts Magnesium and Calcium are the most frequently found
They burn with various colored flame
The name Alkaline Earths derives from the oxides of the elements
Radium was discovered by scientists Marie and Pierre Curie
Interesting Facts

10. Who Discovered The Element
They were discovered in the early 15th century by Sir Humphry Davy
The compound magnesium sulfate was founded in 1618 in Epsom in England by a farmer
In the Scottish village of Strontian, 1790, Strontium carbonate was discovered in minerals

11. Dangers and Precautions
Alkaline Metals are highly flammable with contact with water or moist air
If it were inhaled it can cause severe injury or death
The fire will produce corrosive or toxic gases
Alkaline Metals are:
Water- Reactive
Pyrophoric
