Element Brochure
Research any element you choose and make an
informational brochure to tell about your
element. Creativity may be needed. Technology
assignment (Publisher brochure) Minimum of three
references (one textbook and one internet
site) Title, author, year published and URL Not
ALL writing or not ALL bullets in brochure Use
graphics and pictures to add visual
appeal captions with pictures Front Name of
element, picture/graphic, your name, class
hour Back References, graphic Inside flap
facts melting point, atomic number, Bohr model,
etc Opened brochure (three sectionsinteresting
facts, history, uses)
Brochure should look neat. Writing should be 12
point font. Use only 1 or 2 fonts in entire
brochure.

Autobiography of an Element
I am Promethium, Pm for short. I was named
after Prometheus, who according to Greek
mythology, brought fire to man. I'm a member of
the Lanthanide (rare earth) elements. My family
name is derived from the Greek lanthum, meaning
to escape notice.   You may not have
noticed me around before, as I have no naturally
occurring isotopes. True to family tradition, I
managed to avoid positive identification until
1965. O. Ermetsa first isolated 350 mg 147Pm
from 6000 tons apatite. Once discovered, I was
immediately put to work. Large quantities of
147Pm salts (luminesce pale blue or green) are
used in luminescent paint for watch dials.
Another job I've held is as a part in a
beta-voltaic battery.   You may think
there is not enough of me to go around. However,
everyday, my cousin 147Sm transforms into
Promethium by radioactive decay (at a rate of
0.07/day). Also, I'm a rare earth fission
product of uranium. Please get to know me.
I'll be around for awhile with 147Pm half-life of
2.5 years and 145Pm half-life of 30 years.

Exception!
Two exceptions to the simple ide ending are the
diatomic oxide ions, O22- and O21-.
O22- is called peroxide O21- is called
superoxide.
Note the differences.
