Water is h20 which is 2 oxygen atoms and one hydrogen atom to every bit of water. hydrogen and oxygen are a gas at the time oxygen is made...well as far as i know anyways...but I'm just a very intellegent year 8 student from London!
two or more different elements
They don't have the same elements that make them. Hope it helped. =)
The water molecule contains two different elements chemically combined, which makes it a compound. A compound is a pure substance that contains two or more different elements chemically combined.
two or more different elements
compound is when two or more elements combine chemically
silicon and oxygen
A compound is made when two ELEMENTS are joined together. We can look at the elements in the periodic table from these elements we get really everything that is around us. Water is a compound made from hydrogen and oxygen. There can be different combinations of the elements as this is what makes new things.
A chemical compound is a substance consisting of two or more different elements bonded together in a fixed mass ratio that can be split into simpler substances. Also visit this wikipedia page: http://en.wikipedia.org/wiki/Chemical_compound Just as long as you were talking about a chemical compound and not any other type.
compound
compound is different because it has a dick on it
the thing that makes elements different is the fact that they all have different amount of protons, electrons and neutrons. They all, also, have different mass #'s.
A compound is 2 elements chemically combined, though it is unseparatable, it is made up of 2 or more elements. But since a compound cannot be broken down into elements, after the elements are chemically combined, that makes a compound a pure substance
