    Chemical Elenients—JMctals— Non-metals. sodium, potassium, and sulphur, are found in considerable proportion; some confined to special places, and the others very generally diffused : while, dissolved in sea water, we have, independently of the oxygen and hydrogen of the water, compounds of sodium, chlorine, magnesium, calcium, and potassium, in addition to combinations of about twenty other elements in extremely small proportions. For the sake of convenience the elements are divided into the two classes of metals and non-metals, though the two classes run into each other. Fifty of the elements are commonly reckoned as metallic, and thirteen as non-metallic in their nature. The thirteen elements commonly enume- rated as non-metals are oxygen, nitrogen, hydrogen, carbon, chlorine, bromine, iodine, fluorine, sulphur, selenium, phos- phorus, silicon, and boron. In the following list those of the greatest importance are printed in capitals, as Oxygen. The chemical properties of these we shall examine hereafter; those in ordinary type, as Bromine, will be touched upon less fully; whilst of those in italics, such as Tantalum, owing to their rarity, and the absence of any important application of them in the arts, few will need more than a passing mention.
