Helpful hints: ** Use the ^ symbol to write
orbitals. So the electron configuration for Carbon
is written 1s^22s^22p^2 *** Use the ^ to indicate
exponents and put no spaces between symbols written
in scientific notation. An example would be
2.2x10^-22. **** Write two worded answers using no
spaces. So if your answer is "hot water", write
hotwater in the puzzle.
