chemistry for dummies
Hello, science and non-science folks!
I have a character who's a sciency-type of guy. To calm himself down when he's nervous, he patterns the periodic table in his own ways or plays other games with them.
So, I need y'all to take a test.
Can you figure out why these elements are being listed in their particular orders?
(don't read the comments unless you've commeted or you don't want to guess.)
1. Bromine, arsenic, sulfur
2. Tungsten, astatine, erbium
3. Sulfur, Phosphorus, Oxygen, Oxygen, Nitrogen
4. Radium, Iodine, Sulfur, Iodine, Nitrogen
Thank you!
