Hi!
I originally thought this up as a joke -- a game "Nerds with Friends". However, I thought about it for a second and realized it's crazy enough to work. And I can't find anything similar in the market.
Here's the post that started it all off.
"I can already imagine a new app: Nerds with Friends. In this game, you have tiles with chemical elements and numbers. You have to create compounds crossword style, like with Scrabble. H 2 O would be one thing, and the next player can use C O 2 off the 2. Actually, this sounds crazy enough to actually be a viable game for teaching chemistry..."
There are easy elements like H (1 point) and 1 (1 point). However, once you deal with stuff like 5 (5 points) things get tricky. The inert gases (those that make compounds) are probably 10 or more.
You get bonuses for compounds with more than 2 elements in them.
Thoughts?
There would be a cheat sheet with a periodic table and valences available for the various elements.
Then again, valences don't always help. For instance, everyone knows that C is +/-4 and H is +/-1. According to the the valences, C2H6 (ethane) does not work. Yet it does as two of the C's are connected to each other.
..H H
H-C-C-H
..H H
H2O2 and O3 are also counterintuitive.
H-O-O-H
..O
./ \
O---O
I suppose we can have radicals like SO4 and NO3 too.
