Physical Sci Terms
Vocab for matter
| Term | Definition |
|---|---|
| Matter | Anything that has mass and takes up space |
| Energy Transfer | Changes in states/phases of matter due to an increase or decrease in temperature |
| Compound/Molecule | Two or more element combine together in a specific ratio/pattern creating a whole, new and different substance Example: water H2O 2 Hydrogen atoms + 1 Oxygen atom |
| Mixture | Two or more substances combine together keeping their original properties,they do NOT change into a new substance/compound |
| Atom | smallest part of an element, the building blocks of all matter |
| Electron | particle of atom with a negative charge, moves around the nucleus and has an attractive force that allows it to bond with other atoms creating in the universe |
| Proton | particle of an atom with a positive charge located inside the nucleus |
| Neutron | particle of an atom with a neutral/no charge located inside the nucleus along with the proton |
| Periodic Table | large grid that identifies and classifies all of the elements by their chemical and physical properties |
| Element | the simplest substances that cannot be broken down/ they make up all matter in the universe |
| Periods/rows | rows that tell how many energy levels each elements has for the electrons to move around |
| Groups or Family/Columns | columns that tell how many valence electrons each element has/the number of electrons that can move on its outer shell /energy level |
| Valence Electrons | the electrons that move on the outer shell/energy level of an atom |
| Chemical Change/Reaction | elements bond together through the the attractive force of electrons creating some type of reaction and change |
