Define what an atom is. Then draw/create an atom and label its parts and the charge for each of those parts.

1) Define what an atom is. Then draw/create an atom and label its parts and the charge for each of those parts.

(Bohr structure)

? Proton

? Electron

? Neutron

2) What is the difference between an element, compound, mixture & solution? Give an example of each.

3) Use the Element Oxygen for the next two bullet points.

? Draw/create the element box for oxygen as it appears on the Periodic Table. Label and explain what information each of the following gives you: Atomic Number, Atomic Mass, and Element Symbol

? Now draw/create the Bohr diagram of oxygen

4) Get a copy of the Periodic Table from online (ask if you need help), and then complete the following:

? Color the 3 main sections: Metals, Metalloids, and Nonmetals and create a key for the colors you use

? Label each of the following groups at the top of the column that they are in: Alkali metals, Alkaline Earth Metals, Transition metals, Halogens, Noble gasses

? List the main properties of each of the following: Metals, Nonmetals, Metalloids

? List the main properties of each of the following major groups/families: Alkali metals, Alkaline Earth metals, Transition metals, Halogens, Noble gasses

? If elements are in the same group (column) what does that tell you about them?

? If elements are in the same period (row) what does that tell you about them?

5) Write a short explanation about the way to find the # of valence electrons an element has, and what valence electrons have to do with elements bonding?

? Contrast an ionic bond and a covalent bond (There are 2 main differences)

6) Remember: The Law of Conservation of Matter/Mass is the key to balancing chemical equations. It states that “matter/mass cannot be created or destroyed”…more simply stated, “what goes in, must come out.”

? How will you know when an EOG question is testing your knowledge of this law? Make up a SPECIFIC example of how this question might be worded. (If you cannot make one up, then research online to find one.)

7) Each element on the Periodic Table has its own unique set of properties. Copy or remake the following chart into your slides and then fill in the blank columns.

Property Physical or Chemical Definition

Specific Heat

Density

Malleability

Solubility

Electrical Conductivity

Chemical Reactivity

Flammability

Boiling Point

Melting Point

8) How do you know when a chemical reaction (chemical change) has occurred? List the pieces of evidence we used in class as confirmation that a chemical change had happened over a physical change.

9) Chemical reactions occur at different rates. What effect do the following have on the rate of a reaction?

? Concentration of the reactants:

? Temperature:

? Surface area of solids:

? Catalyst:

Extra Credit: Some chemicals are natural and some are synthetic, what is the difference?
