Shell case pennies are almost identical to regular pennies but contain less zinc. The only two ways to identify the shell case penny and first is to weight them in reference to a normal penny which will be a little lighter because of the higher zinc content. They will also have a much browner tone not reddish. There is no real difference in value just interesting.

H2O is water so if that was the case you couldn’t use or carry a penny. You all ready know the answer.
The formula is 2n2 where n is the principal quantum number (the "shell" number). In this case the second shell has a principal quantum number of 2 so 2X 22 = 8
The three in that sequence lets an observer know how many electrons are filled for that particular shell. In this case, the 2p shell has 3 out of 6 possible spaces filled.
1944s wheat Penny
The 1943 silver wheat penny is made of steel coated with zinc. During World War 2, every bit of copper was needed to make shell casings. Therefore the penny was made out of steel during 1943 so all sources of copper could be used for the shell casings.
