1. Metals

2. Metals
Do Now: Think of a type of metal and describe it’s properties. What does it look like, how does it feel.
Shiny, hard, smooth

3. Metals
All of the elements in the blue squares left of the zig-zag line are metals

4. Physical Properties of Metals
Shiny
Malleability: can be hammered or rolled into different shapes
Ductility: ability to change form without losing toughness
Conductivity: ability to transfer heat and electricity

5. Chemical Properties
Reactivity: ease and speed in which an element combines, or reacts with others
Metals usually react by losing electrons
Some metals very reactive (Group 1)
Some are not-like Gold (Au) and Platinum (Pt)
Other metals fall somewhere in between
Reactivity tends to decrease from left to right on Periodic Table

6. Alkali Metals Group 1 React by losing 1 electron
So reactive they are never found uncombined in nature
As pure elements they are shiny and so soft that you can cut them with a plastic knife
IMPORTANT Alkali metals
Na (Sodium), K (Potassium), Lithium (Li)
v=m55kgyApYrY

7. Alkaline Earth Metals Group 2 Fairly hard Ductile Malleable Gray-white
High melting and boiling point
Good conductor of electricity
Not as reactive as group 1 but more reactive than the other metals
Not found uncombined in nature
Mg (magnesium) Ca (Calcium)
Mg combined with aluminum to make material for ladders, airplane parts, car wheels

8. Transition Metals Groups 3-12 Hard Shiny
Good conductors of electricity
Less reactive
Have high melting and boiling points
Familiar metals
Iron (Fe) Copper (Cu) Nickel (Ni) Silver (Ag) Gold (Au) Mercury (Hg)
Mad as a Matter
D5vKHqtJm-U
Mercury in Fish
Q1ZA8ZrK3U4
Iron reacts slowly with air and water to form rust

9. Mixed Group Metals In groups 13-15, only some are metals
Not nearly as reactive
Familiar metals
Aluminum (Al) Tin (Sn) Lead (Pb)
Lead Poisoning v=76RKSQgduVQ

10. Lanthanides Top row of elements found outside the table Soft Malleable
Shiny
High conductivity
Mixed with other metals to make alloys

11. Actinides Below Lanthanides Uranium is in this group
Used to produce energy in nuclear power plants
All elements after uranium were created artificially in labs
Nuclei are very unstable
So unstable that they only last for a fraction of a second after they are made

12. Synthetic Elements Elements with an atomic number higher than 92
Not naturally found on Earth
Made when nuclear particles are forced to crash into one another
Done with a machine called particle accelerator
