Actinium
This is the very first element in our
series in which will present all the
chemical elements discovered until now
in alphabetical order
Actinium is an element most of us will
never see in person ever
But when enough amount of it is collected Actinium is
soft
silvery white radioactive and
metallic with 89 protons in atomic
nucleus
It is formed in nature by decay of Uranium and Thorium
One ton of the
naturally occurring Uranium ore Autinite
contains approximately 0.2 milligrams of Actium
This is barely the size of a grain of sand
But it is much easier to obtain it in milligrams amounts
from nuclear reactors
by neutron irradiation of the element Radium
The element actinium was
discovered by and by André Louis Debierne
A French chemist in 1899 after he extracted it
from Uranium ores
The Name comes from the 
Greek Aktinos and it means ray or beam
as the element will emit a blue light 
by ionizing the air around it
with its radioactivity, mostly by beta emissions
With sybol Ac Actinium is the
first element of a group called Actinides
with atomic numbers varying from 89 (Actinium)
 to 103 (Lowrencium)
Actinium has a 22,000 year half life meaning half of a
sample will begin to different elements
of the Actinide group within that period
In metal form Actinium will react with water to produce Hydrogen
It also reacts
quickly with oxygen in the air forming a
white coating of Actium Oxide which
stops further oxidation of the sample
Actinium element has no part in life
In laboratory experiments when Actinium
Trichloride was injected in rats
about 33% of the element was
deposited into the bones
and 50% percent in the liver
This is really bad for the victim as
radiation will likely cause cancer
Ironically it can be a good source of
neutrons and an agent for radiotherapy
used in treatments of the same disease
it causes
Actinium is one of the rarest naturally occurring elements
and only trace amounts of it can be found in nature
It occupies the bottom eight
least abundant elements
and it has no significant industrial application
because it is very expensive to produce it.
