But notice that as long as the compound is made of two
different elements, their names end in –ide.
A compound is different from a mixture in that the atoms in a
compound are chemically bonded together, and that’s
why the physical and chemical properties of the compound is
markedly different from the elements from which it is made.
In the next several slides we will look at properties of
some elements and the
compounds they form.
