ELEMENT LIST

We've got 18 to choose from. From the beginning we've been asked, "Why only cover 18?" The rules for the first 18 elements are very straight-forward. (1) Electrons fit nicely into three shells. (2) These elements make up most of the matter in the universe. (3) It's a lot easier to remember facts about 18 elements than over 100 elements.

MORE THAN 18?
Yes, it's true. After these many years, we have added elements 18-36 to our list of elements. You can learn about element origins, pronunciation, atomic structure, and locations. This next set of elements is from the fourth period/row of the table. Be aware... The easy rules don't apply here. We tried to make things as simple as possible.

Element 19: Potassium Element 20: Calcium Element 21: Scandium Element 22: Titanium Element 23: Vanadium Element 24: Chromium Element 25: Manganese Element 26: Iron Element 27: Cobalt Element 28: Nickel Element 29: Copper Element 30: Zinc Element 31: Gallium Element 32: Germanium Element 33: Arsenic Element 34: Selenium Element 35: Bromine Element 36: Krypton
