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.
Diatomic molecules are molecules made of two atoms chemically bonded together. The atoms can be of the same element (homonuclear molecules), or of different elements (heteronuclear molecules). Familiar examples of diatomic molecules of elements are the five gaseous state diatomic elements: Cl 2, F 2 H 2, N 2 ,and O 2.
