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.
A heteronuclear diatomic molecule is made of two atoms of different elements that are joined by a chemical bond. Some molecules that exist as diatomic molecules at room temperature are HCl, CO, CN*, NO*, etc. These molecules are usually polar in nature.
