| Solution | A mixture of one or more substances that cannot be separated by filtration or ordinary settling |
| Hydrogen Bond | Weak bonds between polar molecules |
| Polar covalent bond | bond between two atoms in which electrons are shared unequally |
| Non-Polar Covalent Bond | occurs when two atoms share a pair of electrons with each other |
| Covalent Bond | chemical bond that involves the sharing of electron pairs between atoms |
| Matter | Anything that occupies space and has a mass |
| Mass Number (Atomic Weight) | Number of protons plus the number of nuetrons that an element has |
| radioactive isotope | an unstable atom in which the nucleus decays (breaks down) releasing particles and energy |
| Atomic Number | equals the number of protons that an element has |
| Isotope | atoms having the same numbers of protons but different numbers of neutrons |
| Ionic Bonds | occurs when atoms transfer electrons to other atoms |
| molecule | atoms that are held together by covalent bonds |
