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 of 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 an 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 energy levels each element has/ the number of electrons that can move on the 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 attractive force of electrons creating some type of reaction and change |
Mass | the material/stuff everything is made up of |
Tri- Beam Balance | used to measure mass |
Space | how much volume/area an object takes up |
States of Matter | solid, liquid, gas, plasma, Bose-Einstein Condensate |
Physical Property | changing states or apperance, but not into something new |
Chemical Property | changes that create a whole new substance, it is completely different |
