Non-Metalsin daily life by Akshath S.
What are non-metals? In chemistry, the term non-metals is used when describing the elements in the periodic table. All elements are classified as metals, non-metals, or metalloids (a mix of metals and non-metals)
Did you know? • 18 elements of the periodic table are • considered non-metals, compared to the • 80+ metals • non-metals make up of the Earth’s environ- • ment, including it surface (crust), atmos- • phere, etc. • non-metals can become similar to metals • when large pressure is applied
What are the properties of non-metals? • poor conductors of heat + electricity • when solid, they are brittle, and break easily • luster is usually dull • lower densities, boiling/melting points • (than metals)
Applications of non-metals The Earth’s surface is made of mostly non -metals. The window which you look through, your credit card, car tires, are all composed or contain non-metals. Elements like carbon, which is used in coal, oxygen, which we breath, hydrogen, which bonds with oxygen to produce the water we drink, are all non-metals.
Summary • all elements classified as metals, non-metals, • metalloids • 18 non-metals, 80+ metals within periodic table • makes up more of Earth’s environment • are brittle, dull in luster, poor conductors • elements like oxygen, carbon, and hydrogen • which are essential in our daily life are non- • metals
