| where is the Atomic number and the Atomic mass located | Atomic Number is located in the top far left and the Atomic mass is located at the bottom under the element symbol |
| How do you find the amount of neutrons in an element | Subtract the Atomic number from the atomic mass |
| what are the 3 element diagrams | Bohr-Rutherford Lewis Dot Ion |
| which ions are positive and which are negative? | An Ion is (-) negative and a Cat Ion is (+) positive. |
| What are the three Compounds? | Ionic Compound Poly atomic Compound Molecular/Covelant Compund |
| What is an Ionic Compound? | An Ionic Compound consists of Metals and Non-Metals |
| What is a Poly Atomic compound? | a Poly Atomic compound consists of metals and Poly atomic ions |
| what is a molecular compound? | a molecular compound also known as a Covelant compound consists of Non-Metals and prefixes in their names |
| How do you name a Ionic Compound? | State the Metal State the Non-Metal Change ending of Non-Metal to -IDE |
| how do you name a Poly Atomic Compound | State the Metal State the Poly atomic ion |

| how many equations are there and what are they? | there are 3 and they are: Skeletal Balanced and Word equations |
| what is a skeletal equation? | when it has not yet been balanced |
| what is a Balanced equation | when equation is balanced and has the same amount of atoms for each element on both sides |
| what is a Word equation | a word form equation of reaction happening. (e.g carbon with O2 together react to make ...) |
| how to balance an equation | balance the metals Balance the non-metals (excluding Oxygen and Hydrogen) balance the oxygen's balance the hydrogens |
| how many reactions are there and what are they? | there are 4 and they are Synthesis Decomposition Single Displacement Double Displacement |
| what are the 4 reactions in equation form? | synthesis- A+B-->AB Decomposition- AB-->A+B Single displacement- A+BC-->B+AC Double displacement- AB+CD-->AD+CB |
| what is combustion? | Combustion is the burning of fuel (when fuel reacts with O2) and energy is given off. |
| What is Corrosion? | Corrosion is the break down of metals through chemical reactions. (Rusting) |
