Is an electrically neutral group of two or more atoms held together by covalent chemical bonds

This video takes a quick look at the structures of fats and oils and looks at how they are formed from glycerol (propane-1,2,3-triol) and fatty acids. Stearic acid, oleic acid, linoleic acid (omega 6) and linolenic acid (omega 3) are looked at in some detail.

The quantum model of the atom and the electron orbital clouds s,p,d.

This Chemistry lesson is titled Valence Electrons and the Periodic Table and will give a detailed explanation of the topic.

An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge.

This is a video quiz on the Period Table of Elements.

Elements - a pure substance consisting of one type of atom.

The Organization of the Periodic Table based upon trends of Electonegativity, Eletron Affinity and Ionization Energy.

An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a net positive or negative electrical charge.
