Description

MAIN INSTRUCTIONS:

Chapters 2 AND 3

Start with each checklist (read clearly what teacher expectations are)

1. Read EACH chapter and answer questions at the end.

The question must be written and then the answer.

2. Do NOT do worksheets (skip this section)

3. Choose 4 articles from EACH chapter 2 AND 3 (read, write question and then write the answers)

4. Power point for EACH chapter 2 AND 3 (read directions thoroughly as she made clear to me that she will kick back whatever is not as her directions request)

Introduction
• Oxygen is one of the non-metals in the periodic table. Its outer shell has six
electrons. It is in group number 6 in the periodic table. An oxygen molecule
comprises of two oxygen atoms (O2).

Structure
• Oxygen atom has 8 neutrons, 8 protons, 6 electrons and a total atomic mass of
15.9999 with an atomic number of 8 as shown below:




An oxygen atom cannot exist in its own. Below is an oxygen molecule
consisting of two atoms:

Discussion/Conclusion



Oxygen is an element abundant in the atmosphere
making up to 21%. It is existing as a gas both on earth and
at the galaxy, Moreover, oxygen is present in animals,
plants and water. Oxygen is harvested through a process
known as Cryogenic distillation. Oxygen is present in the
galaxy though in negligible amounts. In addition, plants, human
beings and animals depend on oxygen for a living. Therefore,
oxygen is useful to human beings. Other uses of oxygen include
as an antifreeze, manufacture chloroethene and polyester, and

Chapter 2 Articles
Article 1: Classifying Matter by Physical Properties
1. What is matter?
It is anything that has mass and occupies space.
2. How do characteristic properties help scientist identify substances?
Characteristic properties assist scientist in identifying substances because every substance
has unique characteristic properties.
3. Is the physical property of a substance the same as the characteristic property? Explain
Yes, physical property is same as characteristic property. This is because it comprises of
refractive index, electrical conductivity, boiling point, freezing or melting points, which at
the same time a characteristic property.
4. If a material is a solid, magnetic, a good conductor, and melts at 17280 C, is the material
iron? Explain.
No, the material is not iron because the melting point of iron is 1538 0 C not 17280 C.
5. Complete the table by filling in the physical properties of each object.

Use the table of property to answer the questions:
1. A sound is heard at one end of a piece of iron when the iron is tapped at the other end
with a mallet. No sound is heard at the end of a piece of foam that is tapped at the other
end with a mallet. what property is being tested?
The conductivity of sound is being tested.
2. Circuit: Electrical conductivity is being tested
Look for the bulb to light in case of a good conductor.
3. Magnet: Magnetism is being tested
Look for the spoon being attracted to the magnet if it is magnetic.
4. You put a spoon into a cup of hot cocoa. after a while the spoon is hot. What property
is being tested?
Thermal conductivity
Choice Questions
1. A sample of metal is chopped into pieces. which properties of all the pieces should be
the same?
Characteristic Properties.
2. Which is a poor conductor of heat?
F
3. Which could you use to test the electrical conductivity of a nail?
Circuit

4. what changes when an ice cube melts?
Physical property
5. Pure water does not conduct electricity. But some tap water probably can. Which best
explains this?
Some tap water has minerals, such as iron, in it.
