Non-Metals in daily life : Non-Metals in daily life Onlinetutorsite Inc Welcome’s You The World Of Chemistry
What are non-metals? : 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? : 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? : 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 : 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 : 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
