| Question | Answer |
| Name The Three States Of Matter | Solid, Liquid and Gas |
| Describe What The Particles Of A Substance Are Doing In The Different States Of Matter? (GAS) | Gas: The Particles of a Gas Substance Flow Easily, and The Particles Can Move Past One Another. |
| Describe What The Particles Of A Substance Are Doing In The Different States Of Matter? (LIQUID) | Liquid: The Particles of a Liquid Substance Flow Easily, and The Particles Can Slide Past One Another. These Particles are not Easily Compressible (Little Space Between Particles). |
| Describe What The Particles Of A Substance Are Doing In The Different States Of Matter? (SOLID) | Solid: The Particles of a Solid Substance Don't Flow Easily, and The Particles Cannot Move Past One Another. These Particles are Not Easily Compressible (Little Free Space Between Particles). |
| Name The Processes Of Changing Matter. | |
| Explain Density. | Density is the process that compacts the particles that are in a liquid. It depends whether it has a high or less level of density. |
| Explain Diffusion. | Diffusion is the process when a low concentration of gases is mixed with a high concentration of gas. |
| Explain Convection. | Convection is the process when a heated molecule moves from one place to another taking the heat with them. |
| How To Construct a Graph: | |
| Describe The Structure Of An Atom | Atoms consist of electrons surrounding a nucleus that contains protons and neutrons. Neutrons are neutral, but protons and electrons are electrically charged. |
| What Is A Homogenous Mixture? | Homogeneous - Homogeneous mixtures have the same composition throughout and the individual parts of the mixture are not easily identifiable. Homogeneous mixtures are also referred to as solutions. |
| What Is A Heterogeneous Mixture? | A heterogeneous mixture is made of different substances that remain physically separate. Heterogeneous mixtures always have more than one phase (regions with uniform composition and properties). A mixture of sand and sugar is a heterogeneous mixture. |
| What Is A Pure Substance? | Pure substances are substances that contain only one kind of molecule. |
| What Is The Difference Between An Element, Compound & Mixture? (ELEMENT) | Element: Consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and can exist as either atoms |
| What Is The Difference Between An Element, Compound & Mixture? (COMPOUND) | Compound: Consists of atoms of two or more different elements bound together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means). |
| What Is The Difference Between An Element, Compound & Mixture? (MIXTURE) | Mixture: Consists of two or more different elements and/or compounds physically intermingled, can be separated into its components by physical means. |
| Represent An Element Using Chemical Symbols And Formulae. | Sodium: Na Oxygen: O |
| Represent A Compound Using Chemical Symbols And Formulae. | Sodium Chloride: NaCl Carbon Dioxide: CO2 |
| Explain Difference Between Physical And Chemical Changes: (CHEMICAL) | Chemical Change is when you can't put the object to it's original form. |
| Explain Difference Between Physical And Chemical Changes: (PHYSICAL) | Physical change is when you can change the object back to the original matter. |
| How To Find Number Of Protons? | Atomic Number |
| How To Find Number Of Neutrons? | Mass Number (Bottom Number) Take Away Atomic Number. |
