1. Definitions of Different Elements
By: Morgan Barrow

2. Alkali Metals Alkali Metals are very reactive to water and air
When introduced to air the Alkali metal tends to cover its surface with oxides
Alkali Metals are the first group of the periodic table
The only Alkali metals are Lithium, Sodium, Potassium, Rubidium, cesium, and Francium
Alkali metals lose one electron and form eons with a single positive charge

3. Alkali Earth Metals
The alkali earth metals are sometimes referred to as Alkaline
They have a oxidization number of +2, in turn this makes them very reactive
Because they are so reactive they are not found “free in nature”
The alkali metals are Beryllium, Magnesium, Calcium, Strontium, Barium, and Radium

4. Noble Gases Noble gases are part of group 18 of the periodic table
They are the least reactive elements
This is due to the extremely high amount of valence in its shell
All noble gases conduct electricity, are fluoresce, and are colourless and odorless
The noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon

5. Halogens Halogens are group 7a on the periodic table
They all form negatively charged ions
Halogens means salt former in Greek
Halogens include chlorine, Fluorine, Iodine, and Bromine

6. Non-Metals
Non-metals are located on the upper right side of the periodic table
Non-metals are brittle and not good at conducting heat and electricity
Some are solid and some are gases, but only one is a liquid (Bromine)
The non-metals are as follows Hydrogen, Sulfur, carbon, Nitrogen, Phosphorous, Selenium, and Oxygen

7. Metalloids Metalloids are in-between being a metal and a non- metal
Metalloids are solid at room temperature
Metalloids are brittle, but not ductile
They sometimes conduct electricity and are bad at conducting heat

8. Transition Metals
There are 38 transition metals and are in groups 3 through 12
These metals are both malleable and Ductile
They also conduct heat and electricity
Transition metals have more electrons that they use to combine with other elements
The only transition metals worth mentioning are Iron, cobalt, and nickel
This is because they are the only elements with their own magnetic field

9. Rare Earth Elements
Rare earth elements are natural non-toxic elements that are essential in newer technology
There are 16 REE’s
Even though their called RARE earth elements each is more common in the earths crust then silver
Cerium, Yttrium, Neodymium, and Lanthanum are more common then lead
Even though there plentiful they are not concentrated hence the name

10. Other Metals
most common properties. They are solid, ductile, malleable, good conductors of heat and electricity, high density, and opaque
The other metals are Aluminum, Gallium, Indium, Tin, Thallium, Lead, and Bismuth
All the Other Metals are in groups 13, 14, and 15
All of these are solid
