This is not a lesson dedicated to anything in particular, but several useful ingredients you will need when you make your cake. 



States
To describe the state of a compound, scientists use subscripts.
gaseous = (g)
liquid = (l)
solid = (s)
aqueous = (aq) -dissolved in water

Diatomic Molecules
Some elements occur naturally in the environment as a pair(H2, O2, Br2, I2, F2, N2, and Cl2)

You know how 7 is supposed to be such a lucky number. Well there are 7 diatomic elements, arranged almost like the number 7!  Hope this will help you memorize them!

Other molecules just exist in the environment in large groups.
Some include S8 and P4.
