Arranged in order of increasing atomic number
Good conductors of heat and electric current High luster or sheen (shiny) Solids at room temperature (except for Hg) Ductile Malleable MORE REACTIVE ON LEFT
Variation in properties Not metals Mostly gases at room temperature Generally, poor conductors Solids tend to be brittle
Properties similar to metals and nonmetals Behavior (metal or nonmetal) depends on conditions
When arranged in order of increasing atomic #, elements show similar properties within groups (this has to do with their electron configurations). Group = column Period = row
Most reactive metals: 1 VALENCE ELECTRON Alkali Metals
Less reactive than Group 1A metals: 2 valence electrons Alkaline Earth Metals
Most reactive nonmetals: 7 valence electrons Halogens
“Inert Gases:” 8 valence electrons (except for He – 2) Rarely react because highest energy level is FULL. Noble Gases
Transition metals transition metals
A. Atomic Mass The average atomic mass is the number at the bottom of each square The average atomic mass is the number at the bottom of each square Found.
The Periodic Law –How is the modern periodic table organized? 6. 1.
Notes: Periodic Table Organization. A ____________ is a horizontal row in the periodic table. A ____________ is a horizontal row in the periodic table.

The Periodic Law. Mendeleevs Periodic Table (1872) Dmitri Mendeleev 1 st to publish an organized table of elements. Grouped elements by similar chemical.
5.3 Chemical Families. Elements within the same family of the periodic table have similar properties because they have the same number of valence electrons.
Trends in the Periodic Table The Periodic Table Dmitri Mendeleev ( ) determined the properties of every known element at the time –Atomic Mass.
Elements: one type of atom Classification in the Periodic Table: Groups or Families: have similar characteristics Characteristics: Symbol: 2 letters:
Chapter 6. How does Electron Configuration relate to the Periodic Table?
1 PERIODIC TABLE FAMILIES The is a way of organizing information about elements & atomic structure The Periodic Table (PT) is a way of organizing information.

Look at the following patterns. What are the patterns based on? What do you observe? A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K 1, 4, 9, 16, 25, 36, 49, 64,
The Periodic Table. How Elements Are Organized In 1865 John Newlands was the first to organize the elements according to properties and increasing atomic.
The Modern Periodic Table. 9.How is a keyboard an example of a periodic pattern? On a keyboard there is a repeating pattern of notes. The scale repeats.
COPY. What is the periodic table? compact way of organizing elements contains a lot of information allows us to make predictions about behavior and properties.
Atoms Proton, + charge, 1 amu Proton, + charge, 1 amu Neutron, 0 charge, 1 amu Neutron, 0 charge, 1 amu Electron, - charge, 0 amu Electron, - charge, 0.
Periodic Table The most useful tool in the Lab. Early Organization J.W. Dobereiner (1829) organized elements in triads Triad – three elements with similar.

Periodic Table of Elements. Elements Science has come along way since Aristotles theory of Air, Water, Fire, and Earth. Scientists have identified 90.
Chapter 5 Periodic Table Mendeleev noticed that when the elements were arranged in order of increasing atomic mass, certain similarities in their chemical.
The Periodic Table J. McLeod H. Chemistry. Essential Question How is the periodic table arranged?
Periodic Table Notes Unit 3 – Notes. Periodic Table Nonmetals are on the right side of the periodic table (with the exception of H).
Periodic Table of Elements. Mendeleev In 1869, Dmitri Ivanovitch Mendeléev created the first accepted version of the periodic table. He grouped elements.
