I got this! No problem!
• Use the Periodic Table to identify Metals, Nonmetals, and Metalloids.
• Predict different properties of elements based on
their position in the PT.
• Use the PT to name the elements found in
simple compounds.
• Identify that living things are made mainly of the
elements SPONCH
• Describe Carbon in terms of it’s importance in
living systems
There are three main types of
elements on the Periodic
Table.
METALS
• Most metals are:
shiny
malleable [can be pounded
into thin sheets] and ductile
[can be drawn into fine
wires].
good conductors
Most have high melting points
NON-METALS
are elements are…
-dull.
-brittle, hard, or soft
-Poor conductors.
-tend to have relatively
low melting points.
METALLOIDS
•are substances that
exhibit some metallic
and some nonmetallic properties.
•Some are used as
semi-conductors in
the computer
industry. [e.g. silicon
chips]
What’s so special about C?
What is so special about
Carbon?
1. C is found in many different
compounds. It is in the food
you eat, the clothes you wear,
the cosmetics you use and
the gasoline that fuels your
car.
2. Carbon is the sixth most
abundant element in the
universe.
3. In addition, carbon is a very
special element because it
plays a dominant role in the
chemistry of life.
Other elements in cells…
• 99% of all living
things are made
up of just FOUR
elements: C, H, O,
& N.
• Phosphorus [P]
and Sulfur [S]
make up the 1%.
• Just remember SPONCH!
So you know the elements
in living things…
• SULFUR
• PHOSPHOROUS
• OXYGEN
• NITROGEN
• CARBON
• HYDROGEN
