PERIODIC TABLE TRENDS

Step 1: Complete the squares for each

element by adding the atomic number,

name, and atomic mass.

Write the atomic number at the top of the square.

Write the atomic name under the symbol.

Write the atomic mass at the bottom of the square.

Step 2: Determine the number of electrons, protons,

and neutrons in each statement.

Step 3: Create a Bohr diagram for each element.

(draw protons, electrons, neutrons)

Step 4: Also determine if the element is a solid, liquid or gas

by circling the correct choice.

### Step 5: Show whether the element is a metal, nonmetal, or metalloid by circling the correct response.

Step 6: Use the following colors to shade in the square for each element. You should ONLY color in the small square in the upper left-hand corner and not the entire card.

Green – Li and NaPink – O and SBlue – Be and Mg

Purple – F and ClOrange – B and AlRed – C and Si

Brown – N and PYellow – He, Ne, and ArWhite - H

Step 7: Cut the cards apart and arrange according to atomic number in the pattern shown below. Once you have the cards arranged in the correct order, glue them to a large sheet of construction paper.

Step 8: Put a title on your table.

Step 9: Make a key for each color with the name of the group for that column.

Step 10: Write the column number at the top of each group and the period number on the left side of the table. Be careful, column numbers are not in order from 1-18 and the transition metals, columns 3-12 are not on the table.

Step 11: Draw a red zigzag line that separates the metals from the nonmetals.

Step 12: Answer the questions using the information on your periodic table.

Periodic Table Basics

1. How many elements in your table were:
2. solids _____b. liquids _____c. gases _____
1. Which elements had complete outer shells? (Full number of valence electrons) Give the name and symbol for each
2. ______
1. ______
1. ______
1. What do you think you notice about the location of the elements in question #2?
1. Which of the elements had only one valence electrons? Give the name and symbol for each.
2. ______
1. ______
1. ______
1. What do you notice about the location of the elements in question #4?
1. What do you notice about the valence electrons as you move from left to right across a period or row in the periodic table? (Example: H – Ar)
1. What do you notice about the number valence electrons as you move down a group or column in a periodic table? (Example H – Na)
1. Each column or group in the periodic table is called a family. Elements are organized into families according to their physical and chemical properties. Identify the elements that belong to each family based on the number of valence electrons. Give the name and symbol for each element.

Alkali Metals – 1 valence e- ______

Alkaline Earth Metals – 2 valence e- ______

Boron Family – 3 valance e- ______

Carbon Family- 4 valence e- ______

Nitrogen Family – 5 valence e- ______

Oxygen Family – 6 valence e- ______

Halides – 7 valence e- ______

Noble Gases – 8 valence e- ______

(Complete Shell)

1. Do any of the elements have similar properties? If yes, list the names of the elements and the properties they have in common.

****.Challenge:Predict the number of valence electrons for each element based on its location in the periodic table.

Barium: _____ Lead: _____ Xenon: _____ Potassium: _____

1. Complete the table below :

Group Number / Group Name / Number of valence electrons / Names of elements in that group

16
17
18
1. Hydrogen is placed in group 1 but is not an alkali metal. Why do you think the gas hydrogen is in this group?
1. What trends do you notice about the atomic number and atomic mass as you move left to right across your periodic table?
1. What does the group number help tell you?
1. How do you find the number of electrons and the number of protons in an element?
1. How do you find the number of neutrons in an element?
1. Which two particles are found in the nucleus?
1. Write the names of all the elements on your poster, that are metals.
2. Write the names of all the elements on your poster, that are nonmetals.
1. Write the names of all the elements on your poster, that are metalloids.
