Groups
Groups are columns ( go down) on the periodic table. All elements in the same group or family have similar characteristics such as: reactivity
Elements in a group have the same number of valence electrons

3. 8 # of valence electrons 1 2 3 4 5 6 7 H Li Be B C N O F He Ne Na MgSi P S Cl Ar

Alkali Metals
Group 1 on the periodic table
Have 1 valence electron and are VERY reactive!

7. Topic: Arrangement of the Periodic Table Essential Question: How are elements arranged on the periodic table based on their characteristics?
Halogens
Group 17 on the periodic table
Have 7 valence electrons
They are all just one electron shy of having full shells.
You will often find them bonding with metals and elements from Group One of the periodic table.
