Matter, Phases, Atom
Phases, Phase Changes, Definition of Matter, Atom, Periodic Table basics
| Question | Answer |
|---|---|
| Proton charge and location | positive charge, inside nucleus. |
| Neutron charge and location | neutral charge, inside nucleus. |
| Electron charge and location | negative charge, outside nucleus/electron cloud |
| Element | 94 naturally occurring on earth; can be found as a square on the periodic table |
| Atomic Number | tells you the number of protons and electrons |
| Atomic Weight (mass) | The weight of the protons and neutrons in the nucleus (electrons have almost no weight) |
| Chemical Symbol | Short way of writing the elements name. (1st letter always capitalized, rest lower case) |
| Matter | Anything that has mass AND volume |
| Non-matter | Anything energy. (Heat, sound, light) |
| Temperature | the vibration of the particles, temperature can stop changing and stay the same. |
| Heat | the vibration of the particles, heat never stop moving. |
| Solid | Definite volume and definite shape. |
| Solids move.... | Molecules move in place but cannot overcome the attraction between the molecules. |
| Liquid | Definite volume, but no definite shape. They take the shape of their container. |
| Liquids move.... | molecules are able to slide over each other but particles are still attracted to each other |
| Gas | No definite shape or no definite volume |
| Gas move.... | molecules have very little attraction to other particles and are highly energized. |
| Melting | Solid to a liquid. Heat added |
| Freezing | Liquid to a solid. Heat is removed |
| Evaporation | Liquid to a gas. Heat is added |
| Condensation | Gas to a liquid. Heat is removed |
| Sublimation | Solid to a gas. Heat is added |
| Endothermic | Heat is added |
| Exothermic | Heat is removed |
| What happens to temperature during a phase change? | Temperature stays the same |
| What happens to temperature during the phases of matter? | Temperature goes up or down |
| What are the phases of matter? | solid, liquid, gas |
| What are the phase changes of matter? | Melting, Freezing, Evaporation, Condensation |
