(QUADRUPLE JEOPARDY!!!!) Explain the difference(s) between "AVERAGE", "MASS NUMBER", and "AVERAGE ATOMIC MASS".
An AVERAGE is taken by adding values together and dividing by the number of values added.
MASS NUMBER is the combined number of protons and neutrons in an atom.
AVERAGE ATOMIC MASS is the weighted average of all isotopes of an atom based on an isotope's abundance.

(TRIPLE JEOPARDY!!!) Briefly explain why solid H2O (ice) floats on top of liquid H2O (water).
Due to hydrogen bonding, molecules of solid H2O are spaced farther apart than molecules of liquid H2O. As a result, ice is less dense than water. Ice floats on water.

(DOUBLE JEOPARDY!!) Lithium has an AVERAGE ATOMIC MASS of 6.941 u and has two naturally occurring isotopes: 6Li and 7Li. Identify the isotope that is MOST ABUNDANT and explain why ...
7Li is the most-abundant isotope since the average atomic mass has a value significantly closer to 7 instead of 6.
