1. Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.

2. Bonding types-http://www.dummies.com/education/science/anatomy/4-types-of-chemical-bonds/

3. Conductivity- the degree to which a specified material conducts electricity, Measured in a ratio.

4. electron configuration electron configuration is the distribution of electrons of an atom or molecule

5. polyatomic ionscomposed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit.

6. ionic compounds The opposite negative and positive charges of the ions hold together in ionic bonds, forming ionic compounds

7. Ions an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.

8. Valence electrons are those occupying the outermost shell or highest energy level of an atom while core electrons are those occupying the innermost shell or lowest energy level.

9. Excited electrons-The heat of the flame causes electrons in the metal atom to rise up to higher energy levels.

12. Nuclear reactiona change in the identity or characteristics of an atomic nucleus that results when it is bombarded with an energetic particle, as in fission, fusion, or radioactive decay.

13. Isotopeseach of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

14. Atomic masshe mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

15. Atomic #'s protonsthe atomic number of a chemical element (also known as its proton number) is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus.

16. Evolution of atomic structurehttp://atomictimeline.net/index.php

17. Basic periodic table knowledge

18. Law of conservation states that the total energy of an isolated system remains constant—it is said to be conserved over time.

19. Chemical names and symbols Each element has a one or two letter symbol, which is an abbreviated form of its present or old name.

20. Mass is the amount of stuff in an object, Volumeis the quantity of three-dimensional space occupied by a liquid, solid, or gas. The mass of atoms, their size, and how they are arranged determine the density

21. Matter is everything around you; anything that has mass

22. Tools and Safety is a key concern in any scientific enterprise, but particularly so in the chemistry lab. There are many potential hazards when working with chemicals, but all of them can be avoided with the appropriate precautions.
