2-4 ELEMENTS AND COMPUNDS (cont.)

Because our previous class was shortened, we continued our lesson by learning:

There are many methods in seperating mixtures. Depending on the type of mix, possible methods of seperating mixtures include

• By hand


• Filtration


• Distillation


• Crystallization


• Chromatography

Some elements use Latin. But, there are a few exceptions. Some of those exeptions include:

• Copper= Cuprum


• Gold= Aurum


• Iron=Ferum


• Lead= Plumbum


• Silver= Argentum

Naming chemical compunds is a difficult task. But, the most common system is the IUPAC

• IONS


• BINARY IONIC


• POLYATOMIC IONS


• MOLECULAR COMPOUNDS


• ACIDS

When naming ions, remember that for metals: use the name of your element and add ion. For non-metals, remove the original ending and ade -ide.

Binary Ionic Compounds contain two elements (one metal and one non-metal)

• Metallic and non-metallic bond together
• Electrons trasnfer from metal to non-metal
• Net charge=0 ( total positive charge=total negative charge)

That is all. Mr. Doktor is the best!
