Periodic Table

Group
A column on the periodic table
Period
A row on the periodic table
What are two things that elements in a Group have in common?
1)The number of Valence electrons
2) Similar reactivity
What Group number is the far right column on the periodic table and how many valence electrons do these elements have?
#18
8 valence electrons
These are the Noble Gasses
What is the Group Name of:
Group 1
Group 2
Group 17
Group 18
Group 1: Alkali Metals
Group 2: Alkaline Earth Metals
Group 17: Halogens
Group 18: Noble Gases

Which atom is most likely to give up an electron – Sodium or Oxygen? Why
Sodium. Sodium has a single valence electron. This is far from the stable number of 8 (Noble gas). Oxygen has 6 valence electrons. It wants to get to 8 and doesn’t want to drop back to a lower number.
Benzene has 6 Carbon atoms and 6 Hydrogen atoms. Write the chemical formula.
C6H6
Benzene has 6 Carbon atoms and 6 Hydrogen atoms. Write the structural formula
