Compounds have properties that are different from those of their constituent elements. Can anyone give me an example to support this statement? Thanks!

Ethyl alcohol contains the solid non-metal carbon and two gaseous elements. Yet, the chemical is a liquid with properties nothing like their elements. Ever have a hydrogen martini?

Good question. A great example that I've always used to think about this question is ordinary sand: Silicon dioxide. The properties, uses, and reactivities of its constituent elements are vastly different from the compound itself which can be used to make glass.
Elemental silicon in wafer form is a fundamental component of computer chips because of its semiconductor capabilities. elemental oxygen (not really elemental, but the closes thing you'll find to it) is the most common naturally occurring oxidizing agent, plus we breathe it and all.

The usual favourite..Sodium Chloride...NaCl.
Na & Cl elements examples.
Sodium (Na) is a highly reactive element that, when dropped into water, reacts so violently and exothermically that it will burst into flame.
The reaction produces Sodium hydroxide and Hydrogen.
Chlorine is highly toxic and an irritant to eyes and skin.
Chlorine mixed with benzene will cause a violent explosion,
Na & Cl compound example.
Chlorine chemically combined with sodium becomes sodium chloride ... put it on your dinner....non toxic ..improves taste of the meal.

I cant give you a property but emperically if you're looking at oxidizing numbers, lets say you have O2 gas, it's oxidizing number is zero, but when you place oxygen in a compound where it then becomes an ion oxygen is considered to have an oxidizing number of negative two.

Others have given the example of hydrogen and oxygen. They are correct. Award one of them full points. Hydrogen is explosively flammable. Example: The air ship "Hindenburg," kerboom in New Jersey. Oxygen supports combustion. Just try breathing water, if one is not a fish. Water does not burn, yet it is made of hydrogen and oxygen.

Water is the perfect example.
Hydrogen elements are always found in nature in the gasious state, and so is oxygen. But when the combine to form water they become liquid.

Hydrogen and oxygen are two gases; combined, they form water, which is a liquid.
Sodium is a very reactive metal, chlorine is a very reactive greenish gas; they form sodium chloride: a totally different substance, right?

Water. Both oxygen and hydrogen are gases, but combined as water they are a liquid.
Carbon dioxide is made of carbon and oxygen and is a gas. But carbon on its own is a solid, oxygen a gas.

Water is composed of oxygen and hydrogen which are both gases at room temperature. Water can exist as a liquid at room temperature.

Carbon Dioxide is a gas. Carbon, by itself, is a solid (either graphite or diamond), and oxygen, by itself, is a gas, under standard temperature and pressure etc.
