The Periodic Table

This packet will be practice in the following 8th Grade Standards:

I can describe the structure of an atom and explain how its arrangements affect physical and chemical properties of elements and compounds.

I can explain how the periodic table is arranged based on the physical and chemical properties of element

Lewis Dot Structures:Like Bohr diagrams, Lewis structures (or dot diagrams) show how an atom’s electrons are arranged. Lewis structures focus only on the valence electrons, those electrons in the outer shell. These electrons are the ones that are shared or given away to form bonds with other atoms

Practice: 1. First, use your periodic table to determine how many electrons each element has. Write that number in the lower right

corner (Hydrogen has been done for you)2. Now, to the left of the table, draw a BOHR diagram for each of the elements in the left hand column. 3. Look at the Bohr diagrams you’ve drawn. What do you all 5 elements have in common? 4. Use what you know to complete LEWIS structures for all of the elements. Draw one dot for each valence electron around the

element symbol, following the examples below.

Elements, Compounds & Mixtures Worksheet

Part 1: Read the following information on elements, compounds and mixtures. Fill in the blanks where necessary.

Elements: A pure substance containing only one kind of ____________. An element is always uniform all the way through (homogeneous). An element _____________ be separated into simpler materials (except during

nuclear reactions). Over 100 existing elements are listed and classified on the

____________________.

Compounds: A pure substance containing two or more kinds of _______________. The atoms are _________________ combined in some way. Often times (but not

always) they come together to form groups of atoms called molecules. A compound is always homogeneous (uniform). Compounds ___________________ be separated by physical means. Separating

a compound requires a chemical reaction. The properties of a compound are usually different than the properties of the

elements it contains.

Mixtures: Two or more ________________ or _________________ NOT chemically combined. No reaction between substances. Mixtures can be uniform (called ________________________) and are known as

solutions. Mixtures can also be non-uniform (called ________________________). Mixtures can be separated into their components by chemical or physical

means. The properties of a mixture are similar to the properties of its components.

Part 2: Classify each of the following as elements (E), compounds (C) or Mixtures (M). Write the letter X if it is none of these.

___Diamond (C) ___Sugar (C6H12O6) ___Milk ___Iron (Fe)___Air ___Sulfuric Acid (H2SO4) ___Gasoline ___Electricity___Krypton (K) ___Bismuth (Bi) ___Uranium (U) ___Popcorn___Water (H2O) ___Alcohol (CH3OH) ___Pail of Garbage ___A dog ___Ammonia (NH3) ___Salt (NaCl) ___Energy ___Gold (Au)___Wood ___Bronze ___Ink ___Pizza___Dry Ice (CO2) ___Baking Soda (NaHCO3) ___Titanium (Ti) ___Concrete

Part 3: Match each diagram with its correct description. Diagrams will be used once.

A B C D E

___1. Pure Element – only one type of atom present.

___2. Mixture of two elements – two types of uncombined atoms present.

___3. Pure compound – only one type of compound present.

___4. Mixture of two compounds – two types of compounds present.

___5. Mixture of a compound and an element.

Part 4: Column A lists a substance. In Column B, list whether the substance is an element (E), a compound (C), a Heterogeneous Mixture (HM), or a Solution (S). (Remember a solution is a homogeneous mixture.) In Column C, list TWO physical properties of the substance.

Column A Column B Column C

Color Coding the Periodic Table

Student Worksheet

This worksheet will help you understand how the periodic table is arranged. Your teacher will give you a copy of the periodic table to color. Using map pencils, color each group on the table as follows:

1. Color the square for Hydrogen pink.2. Color the metalloids purple.

3. Color elements 113 and above gray.4. Lightly color all metals green.5. Place one black dot in each of the squares of all alkali metals.6. Draw a horizontal line across each box in the group of alkaline earth metals. 7. Draw a diagonal line across each box of all transition metals.8. Color the nonmetals orange.9. Draw small brown circles in each box of the halogens.10. Draw a royal crown through all the boxes of the noble gases. (example below)

11. Using a black color, trace the zigzag line that separates the metals from the nonmetals.12. Draw two vertical stripes in each square in the lanthanides series.13. Draw a radioactive symbol in each square in the actinide series.

14. When you are finished, make a key that indicates which color and symbols identify each group.
