Compounds
A compound is a substance made
up of two or more elements combined chemically. This combination is similar
to a recipe for a dessert in which one combines the different ingredients in
specific amounts to one another to create a delicious treat!
Compounds are made up of elements
which are a kind of atom or of a combination of compounds. When they are combined
chemically, it is very difficult to separate out the different elements just
as it is very difficult once a cake is baked to separate out the eggs, flour,
sugar and other ingredients.
Compounds often have common names
such as water or salt - but are also named by their formula which tell what
elements make up the compound and in what proportion. For example, the smallest
bit of water, a molecule of water, is made up of two hydrogen atoms for every
one oxygen atom. A formula is similar to a very precise recipe for a compound.
Compounds are made up of many,
many molecules of that compound.
