Physical Properties of some Elements

Here are some elements we introduced in class. I'll expect you to know this information.

Element	Physical Property
	The element hydrogen is a clear, colorless gas.
	The element helium is a clear, colorless gas. All the Noble Gases are clear and colorless.
	The element nitrogen is a clear, colorless gas.
	The element oxygen is a clear, colorless gas.
	The element chlorine is a clear, yellowish-green gas.
	The element bromine is a clear, reddish-brown liquid.
	The element lithium is a soft, gray, solid. Not lithium is harder than sodium and it loks harder. Although is sounds funny to say something 'looks' harder than something else.
	The element sodium is a soft, silvery solid.
	The element potassium is a silvery solid.
	The element rubidium is also a soft, silvery solid. The image to the left is coated with some oxide, giving it a look which is other than silvery.
	The element cesium is also a soft, silvery solid. The image to the left is coated with some oxide, giving it a look which is other than silvery.
