P9+-+Alkaline+Metals

Elements: Beryllium Magnesium Calcium Strontium Barium Radium
 * Alkaline Metals:** Group 2, In the fourth period, Solids

Magnesium- Used to make airplane parts Calcium: Used in tooth paste and vitamins Strontium: Can be mixed into fireworks
 * Common Uses:**

Alkaline metals are not found in free nature because of their reactivity. These elements are found in Earth’s crust, but not in the elemental form because they are so reactive. The metals of Group 2 are harder and denser than sodium and potassium they have a higher melting points.
 * Interesting Facts:**



Magnesium changes color into a brilliant white when heated. Calcium changes into a brick-red. Strontium changes into a crimson when heated. Barium changes into an apple green when heated.
 * Physical Properties:**

Magnesium only reacts slowly with water unless its boling. Calcium reacts fast even when its at room temperature. Calcium, Strontium, and Barium can give off gases when heated.
 * Chemical Properties:**

**The red ones are the Alkaline Metals**
