Good Afternoon 04/20/23• Starter: The periodic table can be

broken up into three general categories. What are they?

• Today we will be learning about the Groups of the periodic table, in what else, Groups!

• Metals, Non-Metals, and Metalloids.

Organization of the Periodic Table• The 18 columns of the periodic table

reflect a repeating pattern of properties that generally occur across a period.

For the Metals, Nonmetals & Metalloids

• In your groups decide who will research the metals who will research the nonmetals and the third will work on Metalloids.

• Your goal is to discover the properties of each, by answering the requirements on the paper. Then report what you’ve learned to the other two people in your group.

• Then we will go over these as a class

For the Groups of the Table• Your group will have to break up

the different groups of the table and list 2 properties or 2 uses or one of each for each of the groups in the table on your paper.

Start of Metals, Non Metals and Metalloids

Metals are Shiny, Ductile, Malleable, good conductors of heat

and electricity.

NonMetals are bad conductors, dull, several are gases. Good

insulators.

Metalloids have properties of both metals and nonmetals and their most useful

property is their varying ability to conduct electricity.

Good Afternoon 04/20/23• Starter: Which group of elements are the

most reactive and why?• Today we will…

– Finish our discussion about the groups of the table and move on to some more interesting aspects.

• Answer: it is the Alkali Earth Metals for the metals and the Halogens for the Nonmentals and they are so very unstable because they are only one electron short of an full outer shell of electrons.

Alkali Metals• Alkali metals are the most reactive

metals and react with atoms of other elements by losing one electron.

• Shiny, malleable, ductile and used in batteries

Alkaline Earth Metals• These are less reactive than group one but

still more reactive than the other metals• Shiny, malleable, ductile, and used in

fireworks and your body.

Melting Points in a Group of Elements

– New element 119 should have a melting point of approximately 25ºC.

• Predicting:– If element number 119

were synthesized, it would fall below francium in Group 1 of the periodic table. Predict the approximate melting point of new element 119.

Transition Metals• Groups 3-12 are less reactive than the

metals in Groups 1 and 2 and therefore found uncombined in nature.

• These are the elements we commonly think of as metals, ductile, shiny, used for coins, some are rare and valuable.

Lanthanides•Lanthanides are soft, malleable, shiny

metals with high conductivity. Used in Movies and To make TV screens.

Actinides• The elements below the lanthanides are called actinides. Many of these elements are so unstable that they last for only a fraction of a second after they are made. They are very radioactive.

Boron Group• Group 13 have mixed properties

and are used in a variety of household products and also in airplanes

Tl

Carbon Group• Group 14, carbon and silicon can

bond with itself and form long chains creating organic molecules.

Nitrogen Group• Group 15, from covalent bonds (sharing

electrons) Nitrogen forms a diatomic molecule (N2) and is 78% of air. Phosphorus is used in fertilzers.

Oxygen Group• Group 16, Oxygen is needed for life,

Selinum is used in copiers and is toxic. Sulfur can form crystals.

The Halogens• The Group 17 elements are the most

reactive nonmetals.

• Like to bond with Alkali Metals.

• Used in toothpastes

Noble Gases• Extremely unreactive, also known as

the inert (not moving) gases.

• They glow when you send electricity through a cloud of them and are used in “Neon” lights.

Hydrogen

• Because the chemical properties of hydrogen differ very much from those of the other elements, it really cannot be grouped into a family.

Isotopes• Atoms of all isotopes of carbon contain six

protons, but they differ in the number of neutrons. Carbon-12 is the most common isotope.

Rules for “Who Wants to be a Millionaire?”

• Teams – There are 4 teams each with a team

name and a captain.– Each Team have a turn answering a

question, the Captain is the only one who can answer for the team.

• The Points– Each question is worth 200 points to

the team that gets it.

Rules for “Who Wants to be a Millionaire?”

• If a team gets a question wrong the first captain to raise their had AFTER I SAY “CAPTAINS” will receive 150 points.

• If the second team gets it wrong then I will say “CAPTAINS” for the two reaming captains and it is now worth 100 points

•  If the third team gets it wrong then I will say “CAPTAINS” for the reaming captain and it is now worth 50 points

Rules for “Who Wants to be a Millionaire?”

• Lifelines were as follows

– 50/50 I will eliminate two wrong answers

– Book Look- 1 minute to look in the book

– Ask the Teacher-Mr. Durand will give a hint

Now your Box on your Table

• Each of you will be given an atomic number you will have to go to the periodic table.

Now your Box on your Table• For this activity please write down the • Symbol (directly in the center and very large)• Name of your element (written under the

element)• Atomic Number (upper Left hand corner)• Atomic Mass (Below the name use 2

decimals)• Your name goes on the back• You should draw it in pencil first and then go

over that with marker

Finding Data on Elements

• Each square of the periodic table includes an element’s atomic number, chemical symbol, name, and atomic mass.
