  • Matter
    Anything that has mass and takes up space
  • Atom
    Small particles that make up the building blocks of matter
  • Nucleus
    Center of an atom
  • Proton
    positively charged particle
  • Neutron
    A subatomic particle that has no charge and that is found in the nucleus of an atom
  • Electron
    A tiny, negatively charged particle that moves around the nucleus of an atom.
  • Substance
    Matter with a composition that is always the same
  • Element
    A pure substance made of only one kind of atom
  • Mixture
    A combination of two or more substances that are not chemically combined
  • Homogeneous Mixture
    A mixture which has uniform composition and properties throughout.
  • Heterogeneous Mixture
    A mixture in which substances are not evenly mixed
  • Compound
    A substance made up of atoms of two or more different elements joined by chemical bonds
  • Solvent
    A liquid substance capable of dissolving other substances
  • Solute
    A substance that is dissolved in a solution.
  • Dissolve
    to mix completely with another substance to form a solution
  • Physical property
    a characteristic of matter that you can observe or measure without changing the identity of the matter
  • Mass
    the amount of matter in an object
  • Volume
    The amount of space an object takes up
  • Melting Point
    The temperature at which a substance changes from a solid to a liquid.
  • Boiling Point
    The temperature at which a liquid changes to a gas
  • Conductivity
    The ability of an object to transfer heat or electricity to another object.
  • Solubility
    A measure of how much solute can dissolve in a given solvent at a given temperature.
  • Density
    Mass per unit volume
  • Electrical conductivity
    The ability of an object to transfer electric current
  • Thermal conductivity
    ability of a material to conduct thermal energy
  • Chemical change
    A change in matter that produces one or more new substances
  • Physical change
    A change in a substance that does not involve a change in the identity of the substance
