Getting to Know The Periodic Table of Elements

Instructions: Check off each step as you complete it. Be sure to use the appropriate colors. It needs to be color-coded.

_____1. Fill each box in the blank chart with the chemical symbol, the atomic mass (the larger number), and the atomic number (the smaller number). Complete this on the large periodic table

_____2. Label the following parts: Complete this on the large periodic table.

A. Period numbers 1-7. B. Group (family) numbers 1-18. C. Zig_zag.

_____3. Color in each of the following groups (families). Each group needs to be a different color. Be careful, some elements belong to more than one group. You must show that. Some elements will not be colored in. Complete this on the small periodic table 1.

A. Alkali metals (blue) B. Alkaline earth metals (green)C. Transition metals (yellow) D. Halogens (orange)E. Noble gases (also known as inert gases). (red) F. Lanthanide series (purple)G. Actinide series (gray)H. Synthetic elements (leave white) I. Legend (Key).

_____4. Trace the metals in blue; trace the metalloids in green; trace the nonmetals in yellow. Complete this on the small periodic table 2.

_____5. Trace the gases in red; trace the liquids orange; trace the solids in purple. Complete this on the small periodic table 3.

_____6. Label the ionization energy trend in blue on the small periodic table 4. Label the electronegativity trend in red on the small periodic table 4.

_____7. Identify other trends and label them on the small periodic table 5. Include a legend and color code them.

_____8. Label the relative size of atoms and ions on the small periodic table 6.

1 Matter & MeasurementsTIME PROBLEMS & DIMENSIONAL ANALYSIS

As chemistry students, you have two goals with problems. First, get the correct answer. Second, be able to show others WHY your answer is correct. Dimensional analysis meets both of these goals.

Dimensional analysis is always a Given value and one or more conversion factors that allow you to determine the Desired value.

Any mathematical fact can serve as a conversion factor. 1 hour = 60 minutes

1 hour60 min or

60 min1 hour

Ex. Convert 1.25 years into seconds.

1. Convert 2.83 days into seconds.

2. Convert 7.72 years into days.

3. Convert 0.0035 weeks into seconds.

4. Convert 180 days into minutes.

5. Convert your age into seconds

Density is often used as a conversion factor between the mass and volume of a sample. For example, the

density of liquid mercury is 13.6 g/mL.

6. What is the volume of a 175 gram sample of mercury?

7. What is the mass of 1.00 gallon of mercury? [1 cup = 236.588 mL]

8. When I carry in a 5-gallon container of water from my car, I always wonder its weight. I looked up on the

web and found that 1 lb = 0.453542 kg and 1 qt = .946353 Liter. Calculate its weight in pounds.
