Matter Weight
Anything that has mass and occupies space. Mass plus the effects of gravity.
Solid Liquid
Definite shape and volume. Definite volume, changeable shape.
Gas Energy
Changeable shape and volume. Capacity to do work or put matter into motion.
Kinetic Energy Potential Energy
Energy in action. Stored (inactive) energy.
Chemical Energy Electrical Energy
Stored in bonds of substances. Movement of charged particles.
Mechanical Energy Radiant Energy
Directly moves matter. Travels in waves (light, X-rays).
Element Atom
Substance that cannot be broken down further. Smallest unit of an element with its properties.
Proton Neutron
Positive charge, found in nucleus. Neutral particle, found in nucleus.
Electron Atomic Number
Negative charge, orbits nucleus. Number of protons in the nucleus.
Mass Number Isotope
Sum of protons and neutrons. Same element, different number of neutrons.
Radioisotope Molecule
Unstable isotope that emits radiation. Two or more atoms bonded together.
Compound Solution
Molecule with two or more different atoms. Homogeneous mixture, evenly distributed.
Solvent Solute
Substance in greatest amount, usually water. Substance dissolved in solvent.
Molarity Avogadro’s Number
Moles of solute per liter of solution. 6.02 × 10^23 molecules per mole.
Colloid Suspension
Heterogeneous mixture, cloudy, does not settle. Large particles that settle out (e.g., blood).
