Periodic Table of Awesomeness (Elements)

Information on Each Element There are 4 main pieces on each square of the periodic table:

Information on Each Element There are 4 main pieces on each square of the periodic table: Atomic Number: The number of protons the Element has

Information on Each Element There are 4 main pieces on each square of the periodic table: Element Symbol: Letter(s) that represent the element.

Information on Each Element There are 4 main pieces on each square of the periodic table: Element Name

Information on Each Element There are 4 main pieces on each square of the periodic table: Atomic Mass: The mass of the atom. Atomic Mass = Protons + Neutrons

Groups/Periods Groups- Vertical columns on Periodic Table

Groups/Periods Period- Horizontal Rows on Periodic Table

Warm Up 12-2 What is the atomic mass of Argon? How many protons does Argon have? How many neutrons does Argon have? If a molecule of Argon lost an electron, what would its atomic mass be? If a molecule of Argon lost an electron, what element would it be? What is another name for the columns on the periodic table? What is another name for the rows on the periodic table?

Metals/ Metalloids/ Nonmetals

Groups with Specific Names Group 1: Alkali Metals Group 2: Alkaline Earth Metals Group 17: Halogens Group 18: Noble Gases

Trends in Periodic Table Atomic Radius – How big the atom is Smallest Biggest

Trends in Periodic Table Atomic Radius – How big the atom is

Trends in Periodic Table Electronegativity/ Electron Affinity– How strongly the nucleus attracts the electrons Strongest Weakest

Trends in Periodic Table Electronegativity/ Electron Affinity– How strongly the nucleus attracts the electrons

Valence Electrons The number of electrons in the atom’s outer shell. This affects how reactive an atom is. This is indicated for each column/group by the number in front of the letter above

Valence Electrons Column/Group 1A has 1 valence electron Column/Group 8A has 8 valence electron (except for He which has 2)

The most common molecules that make up living organisms C H O N P S The most common molecules that make up living organisms Carbon Hydrogen Oxygen Nitrogen Phosphorus Sulfur

Elements that naturally appear in pairs such as O2 Diatomic Elements Elements that naturally appear in pairs such as O2 These are still elements, NOT compounds

Oxidation Numbers These numbers are used to determine chemical formula of compounds. Number is between 0 – 4 Positive number means Group members can GIVE an electron. Negative number means Group members can TAKE/STEAL an electron

Oxidation Numbers +1 - 1 +3 +/- 4 - 3 - 2 +2
