Unit 2 Chemistry: Day 8 Periodic Table of Elements

The Periodic Table of the Elements
BIG Idea
  • An element is a pure substance consisting of only one type of atom with the same number of protons. It can’t be broken down into smaller parts! Some familiar elements are hydrogen, oxygen, gold, aluminum, sodium, helium….
  • Chemists organize matter with the periodic table.  Let’s take a look at a box from the periodic table.
  1. You can draw an atom of any element. 
  2. Look at the atomic number. 
  3. Draw an atom with this amount of protons and of course electrons

Day 9 Periodic Table of Element - Few Elements, Many Compounds Reading Lifework

1 Think of the English alphabet. Millions of words can be made from only 26 letters! The same thing is true of elements and compounds. Elements are the basic form of matter which cannot be broken down any further. A few common elements make most of the planet’s many compounds. Different compounds combine to make all of the things around us. These include rocks, air, water, and even people.

2 Let’s take a trip to Maui in the Hawaiian Islands. You must cross the Pacific Ocean. You travel over seawater made of hydrogen, oxygen, sodium, chlorine, and traces of other elements. Pure water has only hydrogen and oxygen. When you get to the island, you walk on the sand. Sand is tiny bits of worn-out rock mostly made of oxygen and silicon. A breeze hits your face. The air is made of nitrogen, oxygen, a little argon, and carbon dioxide. There are also very small amounts of other gases.

3 As you walk around, you see volcanic rocks and mountains on the island. They are made of mixtures of oxygen and silicon, with magnesium, aluminum, potassium, iron, and small amounts of other elements. Green volcanic rock is also common on the island. It has a heavy concentration of iron and magnesium.

4 You also see all the plants and animals. The Hawaiian Islands contain much diversity. You see many beautiful trees, bushes, and flowers. You see a Hawaiian tree, an orchid on that tree, a beetle crawling on the ground, and a native Hawaiian. These are all examples of living matter made of the elements hydrogen, oxygen, carbon, and nitrogen. Hydrogen is the most abundant element in living matter.

5 As you leave Hawaii, you marvel at what you’ve seen. You are amazed at how so many compounds can be made from so few elements. A few simple elements can combine to make many, many different things.

Directions: Use reading to answer questions:

1 What is the basic form of matter which cannot be broken down any further?

A a compound
B an element
C a chemical reaction
D an organism

2 Which of the following elements do living things have that volcanic rocks do not have?

A Oxygen
B Silicon
C Magnesium
D Carbon

3 Which of the following best summarizes the passage?
A Volcanic rocks and mountains are on Hawaiian Islands.
B Green volcanic rock has a heavy concentration of iron and magnesium.
C Sand is tiny bits of worn-out rock mostly made of oxygen and silicon.
D A few common elements make most of the planet’s many compounds.

4 What is the main point of the reading?
A A few elements combine to make many compounds.
B Many elements combine to make a few compounds.
C Elements cannot be combined except by artificial means.
D Hawaii is made up of only a few types of compounds.

5 The chart above shows the compounds that make up the air. The rectangle on the right is an expanded view of the smallest, black wedge of the pie chart. What percentage of air is oxygen?

A 0.07%
B 0.93%
C 21%
D 78%
