Physical Sci Terms
Science Terms
Term | Definition |
---|---|
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 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 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. |
Period/Rows | Tells how many energy levels each elements has for the electrons to move around. |
Groups Or Family's/Columns | Tells 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 attractive force of electrons creating some type of reaction and change. |
Matter | Anything that has mass and takes up space. |
5 States of Matter | Solid, Liquid, Gas, Plasma, BOE |
Molecules in Different States Of Matter | Solid-Rigid, Fixed Shape/Volume Liquid-Not Rigid, No Fixed Shape, Fixed Volume Gas-Not Rigid, No Fixed Shape/Volume |
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. |
