Physical Sci Terms

Science Terms

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.
