Technetium (Tayler Carter)
1.
2. Technetium was mistakenly
reported as having been
discovered in 1925. At this
time, it was named masurium.
The element was actually
discovered in 1937 by C.
Perrier and Emilio Gino Segre
in Italy.
The origin of the name
Technetium comes from the
Greek technetos, artificial.
3. Technetium is a solid at room
temperature.
The color of technetium is silver/gray.
Melting point: 2200°C
Boiling Point: 4877°C
Density: 11.5 g.cm-3 at 20°C
Technetium is one of only two
elements that has no stable isotopes;
all of them are radioactive. Some
isotopes are produced as uranium
fission products.
4. Technetium was the first artificially
produced element. It was created by
bombarding molybdenum atoms with
neutrons.
Today, this is still how we produce
technetium. When molybdenum
captures a neutron, it decays into
technetium.
The cost of technetium is around $60 per
gram.
5. Technetium-99 is used in
many medical
radioactive isotope
tests. Technetium-99 has
also been proposed for
use in optolectric
nuclear batteries.
One of Techntium's
more useful uses is as a
radioactive tracer that
can be distributed
throughout the body.
