Term | Definition |
matter- | anything that has mass and takes up space. |
energy transfer- | changes in states/phrases 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. ex:water h2o (2) hydrogen atoms + (3) 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 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 nucleus along with the protons. |
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 element has for the electrons to move around. |
groups or family/columns- | columns that tell how many lenience electrons each element has/ the number of valence 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 attractive force of electrons creating some type of reaction and change. |
