Naming chemical compounds can be tricky, and requires a little bit of knowledge about the trends and naming conventions. First, Professor Harman explains that how you name a compound will depend on the type of compound - whether it is an ion, molecular compound, acid, or base. For ions, the way you name the ion will depend on whether the compound is a cation or anion and whether or not it is monatomic, polyatomic, or a transition metal. Anions follow slightly more difficult naming conventions. Molecular compounds use Greek prefixes and will always start with the element furthest from Fluorine. Some molecular compounds have common names (such as water), and these are always used. Bases are simply named like ionic materials. Acids are named based on the suffix of the anion they are derived from. If the anion ends in -ate, the acid uses an -ic suffix. If the anion ends in -ite, the acid uses an -ous suffix.
Taught by Professor Harman, this lesson was selected from a broader, comprehensive course, Chemistry.

Molar Mass and Molarity
Add to EJ Playlist This tutorial shows how to calculate moles and molar mass. I was in a really funny conversation with a teacher about this on 30/4/08.
"Hey [name removed]! Why do people think molarity is so hard?"
"Because they're loosers! I don't really know, molarity's not that hard of a subject, it's just people have trouble grasping it."
Anyways, it took a long time to make this video, so please be nice about it.

Chemistry: Polyatomic ion structures
Add to EJ Playlist Help! Understanding some of the common polyatomic ions.
Chances are good that you've been asked to memorize some of these to be able to name common ionic compounds.
Studying these structures will help you see common bonding trends and understand "what's going on" at a deeper level. :)
(I made this video at 5AM, and I didn't want to wake up my sleeping infant.... sorry about the tired-sounding- voice. :) I couldn't help it!)

Ionic and covalent bonding animation
Add to EJ Playlist Ionic bonding formed when one atom has sufficient strength of attraction to remove ion from the other atom. Covalent bonding occurs when neither atom has sufficient strength to remove the other atom's electron. They would instead share electrons to form stable configurations of electrons.

Lewis Structures (2): Water and Ammonia
Add to EJ Playlist Chemistry Help! Drawing Lewis electron dot structures for water (H2O) and ammonia (NH3).
Instead of using math to account for the valence electrons, I draw all of them on the paper, and "connect the dots!" This way, I don't make silly math mistakes. For more complicated structures, it helps me understand formal charges.
