All the elements in the Nitrogen Family
have 5 electrons in there outermost
energy level
Nitrogen
•
Makes up 1/3 of the
earths atmosphere
• It is a Non metal
• Nitrogen is used to
protect historic
documents
• It was discovered in
Scotland in 1772
• It dissolves in water

forms: white, yellow, red
and black
These forms are used in
fireworks, toothpaste,
detergent, pesticides and
more

Discovered in ancient
times

is a metalloid with
mostly nonmetallic
properties

several gray and black
forms
• it can be poisonous

•
•
Poor conductor of
heat
It is found in 100
mineral species

paper
Most sulfur
compounds have
a strong odor

•
•
•
•
•
can be toxic if handled not
carefully
has a silvery white
appearance
when pure it has a metallic
luster
cost about 100 dollars a
pound
It is added in cast iron for chill
control
used in thermoelectric devices
Polonium
•
•
•
•
Has 27 isotopes, all of
which are radioactive
discovered in1898 by
Polish-French chemist
Marie Curie
she named it after her
homeland of Poland
