Entry Task
Monday, May 13th
Decide if the following statements
are true or false. If they are
true write them down as is, if
they are false write down a
correct statement
1. Groups on the periodic table are
horizontal.
2. As you go from right to left on
the periodic table the number of
protons in each atom increase.
3. Sodium and Francium are in the
same period.
4. Bromine is heavier than oxygen.
Schedule:
• Understand the periodic
table notes
Objective:
I can understand that the
periodic table is a map of
elements organized by
properties
Homework:
• Complete tasks not
completed in class
Things to know before learning
characteristics of groups
Reactive- how likely an element is to undergo a chemical change
Rule of 8
• Elements like to have 8 electrons orbiting in the outside electron shell
• Group numbers can tell you how many electrons are in the outer shell
– Group 1- has 1
– Group 2- has 2
– Group 13- has 3
– Group 14- has 4
– Group 15-has 5
– Group 16- has 6
– group 17- has 7
– group 18- has 8
• If a group has less than 4 they give up their electrons- making them + ions
• If a group has more than 4 they take electrons- making them – ions
• If they have 4 they can do either
• What they do with their electrons determines what other elements they bond with
– Oxygen has 6 electrons and Hydrogen has 1 electron
– H2 O is two hydrogen (2 electrons) and one oxygen (6 electrons) 2 electrons+6
electrons is 8! IT’S A HAPPY MOLECULE!
Metals
• Most elements are metals
• Elements that conduct electricity and heat
well and have a shiny appearance
• Shaped easily by pounding, bending or
being drawn into a long wire
• Solid at room temperature-except for
mercury which is a liquid
Alkali metals
• Metals in group 1 of the periodic table
• Very reactive
• React with air
– When sodium and potassium are exposed to air they
react rapidly with oxygen and water vapor
• Usually lose en electron when bonding with
other elements
• Ions Na+ and K+ are essential for functioning
living cells
Alkaline Earth Metals
• Group 2
• Less reactive than alkali metals but still
more reactive than others
• Lost two electrons when bonding with
other elements
• Calcium ions are an essential part of your
diet
• Magnesium is a strong but light metal
Transition Metals
• Groups 3-12
• Less reactive than other metals but can have some (very
little bit) reactivity
• Metals of the earliest known elements
– Copper, gold, silver and iron
– Gold and silver are easily shaped
• Money is made from these
– dine-and quarters are made of copper and nickel
– Pennies are made of zinc with a coating of copper
• Found in foods you eat
• Two or more can be combined to form an alloy
– Alloy can be stronger and less likely to corrode
– Brass is an alloy of copper and zinc
Rare Earth Elements (Lanthanides)
• Series 58-71
• Called rare earth elements because scientists
once thought that these elements were available
only in tiny amounts on Earth’s crust
• Not so rare- just hard to isolate in it’s pure form
• Europium is used as a coating for some TV
tubes
• Praseodymium is used in welding helmets and
protects from the harmful radiation of welding.
Actinides
•
•
•
•
Series 90-103
Radioactive elements
Very reactive
Thorium and uranium are the only ones
found in Earth’s crust in larger quantities
• Electron sharing is random- no trend
Nonmetals and Metalloids
• Nonmetals– elements on the right of the periodic table
– Properties are opposite of metals
– Their properties vary more from element to element than the
properties of metals
– All are gas in their natural state at room temperature except for
bromine which is a liquid
– Poor conductors of heat and electric current
• Metalloids– Properties of both metals and nonmetals
– Zigzag line that separates metals from nonmetals
– Semiconductors-special materials that conduct electricity under
some conditions and not under others
Chalcogens
• Group 16
• Also known as the oxygen family
• Take 2 electrons when bonding with
another element
• One is radioactive
• Oxygen is what we are most made up of
• Sulfur smells like rotten egg
Halogens
•
•
•
•
•
Group 17
Greek – means forming salts
Very reactive
Non metals
Easily form compounds called salts with many
metals
• Often used to kill harmful microorganisms
• Chlorine
• Iodine used in hospitals
Noble Gases
• Group 18
• Do not give up or take any electrons
• They are considered noble, or inert because
they almost never react with other elements
• Argon gas makes up 1% of the atmosphere
• Colorful lights are made by passing an electric
current through tubes filled with neon, krypton,
xenon or argon gas
