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.
So, a polyatomic molecule is a molecule made up of three or more atoms; which, as in diatomic molecules, may or may not be the same element. Examples of a few polyatomic molecules are P4 (White phosphorus), H2SO4 (Sulfuric acid), SiO2 (Silicon dioxide; sand), H2O (Water) and C12H22O11 (Sucrose; table sugar).
