New learning –notes on periodic table

• 7-4.5 Use the periodic table to identify the basic organization of elements and groups of elements (including metals, nonmetals, and families).

• It is essential for students to know how to use the periodic table to identify the basic organization of elements.

1. A horizontal row on the periodic table is called a period.

2. Families, also called groups, are vertical columns of elements on the periodic table; they are usually numbered 1-18. Elements in the same family have similar properties.

**In the same column means things are in common.**

3. Every periodic table will have a square for each element with the atomic number, atomic mass, element name, and the element symbol.

4.The elements on the periodic table are arranged numerically by atomic numbers.

Atoms• 5. Atoms are made of 3

parts. The proton(+), the neutron(0), and the electron(-) are the three parts.

• 6. The center is called the nucleus and is made of the proton and neutron. Outside of the nucleus is the electron cloud.

• Electron cloud

always — (6-1.5, 7-1.7, 8-1.7) E. hold the heated test tube tightly in your bare hands.F. use the same test tube over and over again.G. use plastic test tubes to keep from cutting yourself.H. point the test tube away from you and others while heating. 3. When working in the lab, when should you notify your teacher?

(6-1.5, 7-1.7, 8-1.7) I. if glassware breaksJ. if you have been injured in the labK. if you do not understand a direction or lab procedureL. all of these are reasons to notify your teacher•

4. Why is it important to test only one independent variable at a time in a scientific experiment? (6-1.5, 7-1.7, 8-1.7)

A. to make the experiment easierB. to save timeC. to find a cause and effect relationship in the

experimentD. to make sure the results gathered are what you

less movement from the earthworms.C. The earthworms do not like light.D. How do earthworms react to light? 9. What is a purpose of a variable in an

experiment? (5-1.2, 7-1.3) E. to serve as the factor that remains the

sameF. to provide the same results as the controlG. to serve as the one factor that gets testedH. to aid in the development of the

hypothesis
