Chemical Symbols are abbreviations for elements.

The Periodic Table of Elements is a tool to identify elements and their properties.

A: WHAT’S THE ELEMENT STATIONS

Copy and finish the text at each station

Write this in your journal and fill in the blanks:

Station 1: The element is ________.Its chemical symbol is ________ One unique thing about it is…

STATION 1 You're breathing right now and your body is

taking in this element. You need it to survive, as do almost all other living organisms. It's a good thing that it makes up over twenty percent of the Earth's atmosphere. We are the only planet in the solar system with enough it available to let us survive. It’s usually found in molecules of two. It’s chemical symbol is O and it is a nonmetal.

Write this in your journal and fill in the blanks:

Station 1: The element is ________.Its chemical symbol is ________. One unique thing about it is…

Oxygen

Oit makes up over twenty percent of the Earth's atmosphere

STATION 2 It is found everywhere in the Universe, but is not found by itself

in nature. You will always find it bound to other elements, such as oxygen (O). You're probably sitting in front of some silicon right now. It's in the computer! Even though humans have been using it for thousands of years, it wasn't discovered officially until 1824 by a scientist named Berzelius. It was isolated and forced to form its first crystals in 1854. When purified, it is a metallic-looking, grayish crystal. While it might be shiny like a metal, it is not a metal. You will find it just below carbon in the third row (period) of the periodic table.

Write this in your journal and fill in the blanks:

Station 2: The element is ________.Its chemical symbol is ________. One unique thing about it is…

Silicon

Si

STATION 3 This is the magic element for everything on Earth. All life

on Earth depends on it. It is in nearly every biological compound that makes up our bodies. It has been known and used for thousands of years. It was never really discovered. Ancient people knew of the black soot left over after a fire (which was this element). It is the sixth element in the periodic table. Located between boron (B) and nitrogen (N), it is a very stable element. Because it is stable, it can be found both by itself and in many naturally occurring compounds. Scientists describe the three states of it as diamond, amorphous, and graphite. It is the same graphite you find in pencils.

Write this in your journal and fill in the blanks:

Station 3: The element is ________.Its chemical symbol is ________.One unique thing about it is…

Carbon

C

STATION 4 It always reminds us of laying out by the pool on a summer

day. There's that harsh little smell that always came from the room with the pool filters. It wasn't always that way. It wasn't until 1774 that a chemist named Davy isolated it as a gas. It's not clear like other gases; it actually has a greenish hue to it. Once Davy purified the element, science was able to prove that it existed in thousands of compounds that we use every day. It makes all of those compounds, because it is super reactive. It's the main component in bleaches. It is the second member of the halogen family (group 17). It's right there in the periodic table with other elements like bromine (Br) and iodine (I).

Write this in your journal and fill in the blanks:

Station 4: The element is ________.Its chemical symbol is ________. One unique thing about it is…

Chlorine

Cl

STATION 5 Being in the first column, sodium is a member of the alkali

metal family with potassium (K) and lithium (Li). It’s big claim to fame is that it's one of two elements in your table salt. When bonded to chlorine (Cl), the two elements make sodium chloride. It is also used as a salt in many fertilizers. Even though humans have been using it for thousands of years, it was not isolated until 1807 by a chemist named Davy. When you purify it, you actually wind up with a silvery bright metal that is quite soft and malleable. It is one of the few metals that will float when it is placed in water . It's atomic mass is less that water's atomic mass of 23 amu.

Write this in your journal and fill in the blanks:

Station 5: The element is ________.Its chemical symbol is ________. One unique thing about it is…

Sodium

Na

STATION 6 It is the first element in the periodic table and the

most basic and common of all elements in the Universe. Over ninety percent of all the atoms in the universe are atoms of this, and they are the lightest of all elements. Although it has been around forever, it took a chemist named Lavoisier to name it. The name comes from the Greek word "hydro", which means water (H2O). Lavoisier knew that it was in all water molecules.. You can also find it closer to home in every organism, blowtorches, and low temperature freezing processes. Write this in your journal and fill in the blanks:

Station 6: The element is ________.Its chemical symbol is ________. One unique thing about it is…

Hydrogen

H

C: 1. The element I found the most

interesting was ______ because __________.

2. The element I think is the most important to my survival is _______, because…

3. The least important element is __________ because…
