The Periodic Table
The Periodic Table
The Table in General
• Columns – Called _________________– Elements in a family have similar __________
& ______________ properties– As you go from the top to the bottom of the
column the elements get _______________.
Draw an arrow down Column 1
The Table in General• Rows
– Called _______________– First element in a period is a very _________
____________________________________– Last element in a family is a very _________
____________________________________– Elements get less _______ as you move right
• Reactive means to loose electrons
– Elements become less __________________ as you move to the right
Draw an arrow across period 4
Alkali Metals
• ________ electron in the valence shell– Valence means the ____________ shell
• Soft less dense metals• Most reactive of all metal
– Reactive means ___________________
• React with __________ to form bases• Never found free, ________, in nature• Used to make soap, salt, baking soda
Alkaline Earth Metals
• _______ electrons in the valance shell
• Harder, higher melting point, more dense than ___________ (column 1)
• Very reactive
• Never found free in nature
• Free means_____________________ ______________________________
Transition ElementsCircle any element in this area that you can
name a use for.
Transition Elements• ___________ conductors of heat and electricity• Higher melting point than first two families• The first two families are:
1. _________________ 2. _______________• Some are ____________ & _______________ • Some combine with oxygen to form oxides• Form brightly colored compounds• List items that are made from transition elements:

___________________________________________________________
• 2nd Row Actinide Series – all but three are synthetic: _____________________________.– Box the ones you know. What are they used for?
___________________________________________________________
Boron Family
• Three electrons in the valance shell• The valence shell is the ____________
____________________________________• Collection of "odd ducks"
– boron is a metalloid – aluminum, gallium, indium and thallium are poor
metals
• Aluminum is the ______________ most abundant element on earth.
Carbon Family
• ___________ valence electrons• Form organic compounds
– Organic means ___________________
• Silicon is the _______________ most abundant element on earth
• Tin resists Oxidation and Corrosion– Oxidation is ______________________– Corrosion is ______________________
• Lead is very dense and poisons
Nitrogen Family
• Five electrons in the Valance shell.

• Phosphorus: _______________
• Arsenic: Rat Poison
Oxygen Family
• ____________ outer electrons • Oxygen _________________, which
means that _____________________ and is very reactive, combines with many other elements
• Sulfur, Selenium, Tellurium: __________, which means that ______ _______________________________ combine easily with other elements
Halogen Family
• ___________ valence electrons.
• Most chemically reactive ____________
• Never found free or _________ in nature
• ________ melting and boiling point

• Colorless odorless gas at room temperature
Follow the following directions.
• Draw in the step ladder.
• Mark the Metalloids with diagonal lines.
• Mark the non-metals with dots.
• Be sure that the key on the next slide is filled in with the color and the name of the family.
