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 elements combine together in a specific ratio/pattern creating a whole, new and different substance. |
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 everything 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 valance electrons each elements has/the number of electrons that can move on its outer shell/energy level. |
Valance electrons | The electrons that move on the outer shell/ energy level of an atom |
chemical change/reaction | Elements bond together through the attractive force of electrons creating some type of reaction and change. |
Tri-beam balance | an instrument that is used to measure mass |
