Guessing Ions From Periodic Table

"Guessing" isn't quite the right word. More like "know". Once again, this is something that you're going to have to learn by next week anyways, so might as well do it BEFORE the test so that... Well, you don't get points for learning something AFTER the test, do we.

Overview of Groups, Families & Brinklehoff (BrINClHOF)

Halogens, Alkalai Metals, Alkaline Earth Metals, Transition Metals, and Noble Gases: these are all annoying names you'll memorize over the next month whether you want to or not. One thing you will want to memorize, because you'll lose so many points if you don't, is BrINClHOF, the popular acronym for the diatomic gases! Yay!

Guessing Ions From Periodic Table

This chapter shows you what everything on the periodic table means, including the families such as Alkalai Metals, Alkaline Earth Metals, Halogens, Transition Metals, and Noble Gases. It also explains how to tell which ions atoms form.

Solid vs Liquid vs Gas

In Chemistry class it's easy for teachers to get so bogged down in the details of whatever vocabulary-packed topic you happen to be studying that the "big picture" goes unnoticed: ultimately, everything in chemistry is about bouncy little magnets (atoms and molecules) either sticking together (solid) or rattling apart (liquid and gas).

Substances vs Mixtures

This isn't a super-exciting topic, but it will be on your quiz, so listen up!

These videos are an intro to chemistry. First we'll explain what the heck atoms, molecules and compounds are, then we'll explain how temperature makes a bunch of molecules decide to go from being a solid, to liquid, to gas.
