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.
2. Because some of the diatomic elements are gases that all gaseous elements (or even molecules) must be diatomic. Only five of the diatomic molecules are gases at room temperature. Bromine is liquid and iodine is a solid at room temperature. All noble gases are monoatomic.
