What is the Periodic Table?
• It is an organizational system for elements.
Picture from www.chem4kids.com
Why is the Periodic Table Important?
• The periodic table is the most useful tool to a chemist.
• It organizes lots of information about all the known elements
http://www.youtube.com/watch?v=lDp9hUf_SV8&edufilter=vH8ntV7keCE-ZLl5wRMzNg
Remember that an Element
• Is a pure substance made up of one kind of atom that cannot be broken down into simpler substances by physical or chemical means
• 90 occur naturally on earth• 25 were synthesized (made) by
scientists
http://www.privatehand.com/flash/elements.htmlhttp://www.scienceraps.co.uk/rap_science_periodic_table.html
Who created the it?
Dmitri MendeleevIn 1869, Russian chemist Dimitri Mendeleev proposed arranging elements by atomic weights and properties.

Why do you think there are question marks here?Image taken from: http://www.chemsoc.org/networks/learnnet/periodictable/post16/develop/mendeleev.htm
Mendeleev’s Published Periodic Table of Elements
Who was Henry Moseley?
• Arranged elements by atomic number instead of mass
• Realized that there were undiscovered elements
Image taken from: http://dewey.library.upenn.edu/sceti/smith/
So how is it arranged?
• The genius of the periodic table “is that it is organized like a big grid. The elements are placed in specific places because of the way they look and act. If you have ever looked at a grid, you know that there are rows (left to right) and columns (up and down). The periodic table has rows and columns, too, and they each mean something different.”
•quoted from http://www.chem4kids.com/files/elem_pertable.html
Periods =Rows• Even though they skip
some squares in between, all of the rows go left to right. When you look at a periodic table, each of the rows is considered to be a different period (Get it? Like PERIODic table.)
•quoted from http://www.chem4kids.com/files/elem_pertable.html
Groups=Columns
• The periodic table has a special name for its columns, too. When a column goes from top to bottom, it's called a group.
•quoted from http://www.chem4kids.com/files/elem_pertable.html

MetalsLocation
• Found on the left of the zigzag line/staircase on the periodic table
Chemical Properties• Reactivity- ease and speed
with which an element combines with other elements or compounds
• Have few electrons in their outer energy level, thus lose electrons easily
Physical Properties• ductile, good conductors of
heat and electricity, malleable, shiny, most are solid @ room temperature What metal is not a solid
@ room temperature?

How many
periods (rows)are on the
Periodic Table
Of Elements
?
Period (Row) Properties• Seven periods on a periodic table (numbered
from the top down)• Atomic numbers and atomic masses increase
as you move from the left to the right in a period
• All atoms of the elements in the same period have the same number of orbitals/levels– Example
• Period 1 = 1 orbital• Period 2 = 2 orbitals• Period 3 = 3 orbitals
• Etc…
Examples of Period (Row) elements having the same number of orbitals/levels in their atoms

How many groups (families)
are on the Periodic Table Of Elements?
Group (Family) Properties• 18 groups (numbered
from left to right) • Atoms of elements in the
same group have the same number of valence electrons
Exceptions: • Transition elements
(3-12) • Helium (actually has
2 valence electrons)• Elements in groups
usually have similar physical and chemical properties
• Families have names rather than numbers (just like your family)
Examples of Group 1 Elements with the same # of valence electrons

Using the Periodic Table• The boxes that make up the periodic table contain a
significant amount of information. To understand this information, it is necessary to refer to the periodic table’s key(s)
Atomic Number (Number of protons)
Element Symbol(Written with a capital letter or a capital followed by a lower case if two letters )
Atomic Mass(Rounded to a whole number, equals the number of protons and neutrons)

Which class does Oxygen
fall into?
What is Oxygen’s physical state of matter?
Element Name
Hydrogen
• Hydrogen belongs to a family of its own.
• Rarely found as pure element, mostly in H20
• Hydrogen is a diatomic, reactive gas.
• Hydrogen was involved in the explosion of the Hindenberg.
Alkali Metals• Group 1 Elements:
(not including Hydrogen)
Lithium, Rubidium Sodium, Cesium Potassium, Francium
MOST reactive metals, never found uncombined in nature (like in salt).
• 1 electron in the outer shell
• Soft and silvery metals• Conduct electricity
Alkaline Earth Metals
The Group 2 ElementsBeryllium, Magnesium, Calcium Strontium, Barium ,Radium• 2 electrons in the outer shell• White and malleable• Reactive, but less than Alkali
metals• Conduct electricity
• Several of these elements are important mineral nutrients (such as Mg and Ca)
Transition Metals
• Elements in groups 3-12• Less reactive, harder
metalsGood conductors of heat and
electricity.Some are used for jewelry.The transition metals are able to
put up to 32 electrons in their second to last shell.
Can bond with many elements in a variety of shapes.
Boron Family
• Elements in group 13
Boron ,Aluminum, Gallium, Indium, Thallium
• Aluminum metal was once rare and expensive, not a “disposable metal.”
• Elements have 3 valence electrons.
• All are metals except Boron (metalloid)
• Aluminum is the most common metal in the Earth’s crust.
Carbon Family
• Elements in group 14Carbon, Silicon,
Germanium, Tin, Lead• Contains elements
important to life and computers.
• Carbon is the basis for an entire branch of chemistry.
• Elements have 4 valence electrons
• Silicon is used to make semiconductors for computers and other electronics .
• Diamond and Graphite are two forms of carbon.
Nitrogen Group
• Elements in group 15
• Nitrogen makes up over ¾ of the atmosphere.
• Nitrogen and phosphorus are both important in living things.
• The red stuff on the tip of matches is phosphorus.
• Elements have 5 valence electrons
• Can share electrons to form compounds
• Contains metals, metalloids, and non-metals
Oxygen or Chalcogens Family
• Elements in group 16Oxygen, Sulfur, Selenium,
Tellurium, Polonium• Oxygen is necessary for
respiration.• Many things that stink,
contain sulfur (rotten eggs, garlic, skunks, etc
• About 20% of the Earth’s atmosphere is oxygen.
Halogens
• Elements in group 17• Fluorine, chlorine,
bromine and iodine• Very reactive, volatile,
diatomic, nonmetals• Always found combined
with other elements in nature.
• Used as disinfectants and to strengthen teeth.
• The Halogens form salts with the alkali metals.
• Fluorine is an active ingredient in toothpaste
The Noble Gases
• Elements in group 18
Helium, Neon, Argon, Krypton, Xenon, Radon
• VERY unreactive, monatomic gases
• Used in lighted “neon” signs
• Do NOT ordinarily form compounds.
• Have a full valence shell
The Lanthanides and The Actinides
• The Lanthanides• Soft metals that can be
cut with a knife.• Were once called rare
earth metals.• Glass used in computer
and TV screens contain Yttirum and Europium
• The Actinides• All actinides are
radioactive.• Thorium, Proactinium
and Uranium are the only actinides found naturally on earth.
• Plutonium is used to fuel nuclear power plants.
What is an ION?
• Charged atoms (or groups of atoms) are called ions.
• An atom becomes charged by either gaining or losing one or more electrons.
• An atom that has lost one or more e- is a positive ion or (cation). The atom now has more protons than e-.
• An atom that has gained one or more e- is a negative ion (anion). The atom now has
more e- than protons.
Cation or Positive Ion
Anion or Negative Ion
