element- A pure substance made of only one kind of atom - Predictable, usually - Matter made up of one type of atom - It is better to have either full or empty shells in order to have stability. A half-filled shell is unstable compoundA pure substance made up of atoms of two or more different elements joined by chemically extensive propertydepends on the amount of matter that is present, (sample size matters) intensive propertyproperties that do NOT depend on the amount of matter pre...

Allows us to determine the molecule mass and the molecular formula of a compound, as well as some of it's structural featuresMass Spectrometry Tells us the kinds of functional groups a compound hasInfrared (IR) Spectroscopy Provides information about the carbon-hydrogen framework of an organic compoundNuclear magnetic resonance (NMR) spectroscopy A very small sample is placed in a mass spectrometer, where it is vaporized and then ionized (electron removed from each molecule). Electron ...
