There's no mess with soil or compost - all you need is a jar and an airing cupboard to grow Chinese bean sprouts, also known as mung beans, which may not be as long as the ones you buy in supermarkets, but they'll be just as tasty.
Best Answer: Polyatomic: The only difference between a polyatomic ion and a normal ion is that a polyatomic ion is composed of more than one elements. The elements are chemically bonded and have an overall net charge like a normal ion.
If the two atoms are identical, as in, for example, the oxygen molecule (O 2), they compose a homonuclear diatomic molecule, while if the atoms are different, as in the carbon monoxide molecule (CO), they make up a heteronuclear diatomic molecule. Molecules containing more than two atoms are termed polyatomic molecules, e.g., carbon dioxide (CO 2) and water (H 2 O). Polymer molecules may contain many thousands of component atoms. A water molecule is made up of two hydrogen atoms and one oxygen atom.
