1. Divide the squares into 4 piles of like colors

2. Number each square in each pile (1-10)

3. Mix up the squares, make sure the numbered sides are facing up

4. Have partner 1 name a square by color and number.

5. Have partner 2 find that square. Repeat steps 4-5 twice

(you may switch roles)

6.Rearrange the squares into four rows, one for each color.

Order the squares in each row from 1-10

7.Repeat steps 4-5 four times (you may switch roles)

Which was easier? Which method took less time?

Why were the times different?

Why did you do this activity?

Look around in your science classroom… do you recognize squares set together in this same

?

What is it called!?

Sure, it’s the Periodic Table… But do you really know what each of those squares represent?

…And do you really know why those squares are set the way they are?

Each square represents an element .

What is an ELEMENT?

a pure substance that cannot be broken down into a simpler substance by physical or chemical means

Each square represents an element.

Examples of familiar elements include…

ALUMINUM SULFUR

NITROGEN

(in liquid state)

Each square represents an element.

Examples of familiar elements include…

URANIUM MERCURY

COPPER

Each square represents an element.

Examples of familiar elements include…

SODIUM SILVER

CARBON

BEFORE scientists began to sort out the elements, what was thought was much different than today.

For hundreds of years, even until the late 1700’ s , people believed that there were FOUR PRIME

ELEMENTS that made up all things that existed.

Well, it’s been only a little over 200 years since a few certain scientists began to classify and organize the elements that were known at that time.

The Periodic Table can be of thought of as just like looking at a map of the United States of America.

A METAL is any elementary substance that is crystalline when solid , and is also characterized by malleability, conductivity , and a unique luster .

Some examples of METALS are…

Magnesium Cesium

Cobalt Titanium

A NONMETAL is any elementary substance

NOT having the characteristics of metals .

Some examples of NONMETALS are…

Carbon Iodine

Bromine Neon

A METALLOID is any element whose properties are intermediate or between those of metals and solid nonmetals. They are electrical semi-conductors.

Some examples of METALLOIDS are…

Antimony Silicon

Tellurium Germanium

Now, let’s take a look at the single squares that represent those elements.

The Periodic Table will display at least these

FOUR parts to give you the basic rundown of each specific element.

Now, let’s take a look at the single squares that represent those elements.

The number at the TOP of each square is called the ATOMIC NUMBER .

This number stands for how many protons that this type of element holds within its nucleus.

PROTON - a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign .

Now, let’s take a look at the single squares that represent those elements.

Elements whose SYMBOLS differ from their names…

 NAME – SYMBOL – OLD NAME

 Sodium – “Na” – Natrium

 Potassium – “K” – Kalium

 Iron – “Fe” – Ferrum

 Copper – “Cu” – Cuprum

 Silver – “Ag” – Argentum

 Tin – “Sn” – Stannum

 Tungsten – “W” – Wolfram

 Mercury – “Hg” – Hydragyum

 Lead – “Pb” – Plumbum

 Antimony – “Sb” - Stibium

The ONE or TWO letter

SYMBOL that appears in the center of the square is a way to represent that specific element in a shorter way. The letter (s) are either part of the element’s name or from its original Latin name.

Now, let’s take a look at the single squares that represent those elements.

The NAME of the element! According to the IUPAC*, “elements can be named after a mythological concept, a mineral, a place or country, or a scientist.”

* IUPAC – the International Union of Pure and Applied Chemistry. This is an organization that strives to advance chemistry, in part by setting global standards for names, symbols, and units.

Now, let’s take a look at the single squares that represent those elements.

The number at the BOTTOM of each square is called the

ATOMIC MASS . This number stands for the mass of an atom of an element. It is about equal to the number of protons and neutrons in an atom of the element.

The Atomic Number shows the # of protons. So, that means…

NEUTRON - a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary Hydrogen.

So, what are the names of all the elements?

Some of them are kind of wacky!

Here’s a song that can help you learn their names!

So, what are the names of all the elements?

As you can see from the video, the elements are also broken into smaller sub-sections, each called a FAMILY.

(rather than just the Metals, Nonmetals, and Metalloids)
