Metals!! Alkali, Alkaline, Transition, Metals in Mixed Group, Lanthanides, and Actinides

Alkali Metals Group 1 on the periodic table Alkali metals react with other elements by losing one electron They are soooo REACTIVE that they are never found alone in nature. Soft and shiny, you could cut it with a plastic knife.

Examples: **Lithium – found in batteries and medicines. **Sodium and potassium are good for our health. -Sodium is found in seawater and salt beds. -Potassium is in spinach, baked potato with skin, plain yogurt and fish

Group 2/starts with Berylium) Reacts by losing 2 electrons Also found combined in nature. Gray and white Fairly hard Good conductors of electricity

** Calcium – is found in yogurt, milk, all dairy products, green leafy vegetables. It gives us strong bones. ** Magnesium – When we mix Mg with aluminum it creates a strong but lightweight material that’s used to make ladders, airplane parts, and car parts.

Transition Metals

  Groups 3-12. Some famous transition metals are: gold, platinum, silver, iron, mercury, Hard and shiny Good conductors of electricity Form colorful compounds Not so reactive

Gold: very precious metal because it’s not reactive **Iron: iron produces hemoglobin which carries oxygen into our bloodstream.

Metals in Mixed Group Groups 13 -15 Some are metals- not all! ( MIXED) Less reactive Aluminum, tin, lead

Aluminum – lightweight metal used in beverage cans and airplane parts Tin - a thin coating of tin protects steel from corrosion in cans of food. Lead – it was once used in paints and water pipes. Since it is poisonous, it is no longer anymore. Now, it is used in car batteries and tires.

Lanthanides Actinides

Lanthanides Soft Malleable Shiny High conductivity They are mixed with more common metals to make alloys. Alloys- 2 or more metals mixed together They are difficult to separate because they all have very similar properties.

Actinides Only 4 actinides are found in nature. Uranium 238 is used in a power plant to create nuclear energy. The rest of the actinides are not found in nature. They are created in a lab, they produce a great amount of energy, and then they fizzle out. The energy is captured by scientists.
