Periodic Table of ElementsNotes and ReviewK. Spence
+Essential Questions
How is matter organized?
How does matter differ in composition and properties?
How can you differentiate between types of matter qualitatively and quantitatively?
What methods and properties are used to organize elements?
+Objectives:
Students will be able to:Explain how elements are organized.Distinguish between families and
groups.Identify elements with similar
properties.Label large groups of elements.Predict properties of the substance or
position on the table based on given patterns.
+Vocabulary:
Element- a single kind of atom
Atom- smallest, basic unit of matter
Period- Horizontal Rows on the periodic table
Group/Family- Vertical Columns; elements in the same group have the same number of electrons in the outer orbital; react in similar ways because they bond in similar ways
Atomic Number- number of protons in the atom
Atomic Mass- number of protons and neutrons in the atom (average mass of all atoms of that kind, including isotopes)
+
Element- Fundamental substances that cannot be broken down into simpler substances by normal chemical reactions.
118 known elements 92 Naturally occurring elements No Unknown elements under 110
Earth’s Crust Human BodyO 49.5% O 65%Si 25.7% C 18%Al 7.5% H 10%Fe 4.7%

Mendeleyev Challenge
How would you organize so many elements?
+History of the Periodic Table - Youtube
Periodic Table of Elements
Dmitri Mendeleev Lothar Meyer
Periodic Table of Elements
A draft of Mendeleev’s first periodic table created in February 1869.
Lothar Meyer also published a table in 1870 but did not predict the existence of undiscovered elements.
Periodic Table of Elements
Mendeleev’s first periodic table published in Zeitschrift für Chemie 12, 406-6 (1869)
+Importance of Mendeleev’s Table- Youtube
+Modification to Mendeleev’s Table: All atoms of the same element contain the
same number of protons.
Atomic Number- number of protons in an atom.

Metalloids
+Metalloids
Metalloids• Elements with intermediate properties. • Have characteristics of metals and non-
metals• Some are shiny, some are dull• Many are good conductors, but not as
good as metals• Border separation between metals and
non-metals. ex. Al, Ge, As, Sb, Te…
+Color the Periodic
Table Activity
Pay Close Attention to Details and Labels… The actual colors don’t matter,
but shading and different colors are necessary.

Alkali Metals
+Alkali Metals
Highly Reactive Group (most reactive metals)
Like to “give away” 1 electron because outer orbital has one lone electron.
Not usually found alone in nature – found combined with other elements.
Solids at room temperature, but soft metals, can cut with a knife.

Like to “give away” 2 electrons because outer orbital has two lone electron.
Not usually found alone in nature – found combined with other elements.
Harder and denser.

+Valence Electrons
Valence Electron- electrons in the outer “ring” or shell of an atom.Valence electrons are important for
chemical reactions and bonding as well as reactivity.
Elements in the same group will have the same number of valence electrons.
Each period has more energy levels or “rings” of electrons.
How many Valence Electrons in each atom?1 4 5 6
• Notice that the atomic number and the number of valence electrons are NOT Equal.
• Atomic Number stands for the number of protons. • If the atom is uncharged (Not an Ion) the number of
protons = the number of electrons.
Ion or Neutral Atom?
