Group 1 Alkali Metals
Group 1 contains all metalsThey are VERY reactive. They are only found
combined with other elements since they are so reactive.
They have a low density, are soft, and are silver colored.
One Electron in outer shell
Potassium
Sodium
Group 2 Alkaline Earth Metals
Group 2 contains all metals
The are VERY reactive, but less reactive than group 1.
They have a low density, and are often mixed with other metals.
Two Electrons in outer shell
Magnesium
Group 3-12 Transition MetalsGroup 3-12 contains all metalsThey are less reactive than groups
1 and 2.
They are good conductors of thermal energy and heat.
The properties of transition metals varies among the different elements.
TitaniumMercury
Gold
Group 13 Boron Group
One Metalloid (semi-metal) and 4 metals
They are reactive, yet less reactive than groups 3-12
They are all Solid at room temperature.
They have 3 electrons in their outer shell.
Aluminum
Aluminum
Group 14 Carbon Group
1 nonmetal, 2 metalloids (semi-metals), 2 metals
They are all Solid at room temperature.
4 Electrons in Outer shell
Tin Wire
SiliconLead
Group 15 Nitrogen Group
2 nonmetals, 2 metalloids (semi-metals), 1 metal
They are all Solid at room temperature except for Nitrogen which is a gas.
