Basic knowledge about Xenon

On Monday classes, Mr.Shamsul touch a little about Xenon. So,now...I would like to write something here as our knowledge. Let's check it out!!!

Xenon?
From my research, Xenon is also called ' STRANGER'. It name originates from the Greek word ' XENON'. Xenon is colorless, orderless, highly unreactive gaseous ( found in minute quantities in the atmosphere).

Characteristics of Xenon

Element  :Xenon (Xe)
Atomic no  : 54
Atomic mass   : 131.29 amu
Melting point : -111.9° C (-161.25°K)
Boiling point  : -108.1°C ( -165.05°K)
Neutron in Xenon  : 77
Crystal Structure   : Cubic
Color of  Xenon    : Colorless
Periodic Table: Group 18 ( Noble gases)




Did you realize?
If you realize, Xenon is commonly used as photographic strobe light ( lens camera,alarm light, arc lamp and etc). 

Xenon-135
Xenon is occurring consist of nine stable isotopes. For Xenon-135 is produces as a result of nuclear fission and acts as a nuclear absorber in nuclear reactor.

How it produce?
Xe135 is produced directly from fission and from the BETA decay of Tellurium-135, as shown below.
Xe-135 subsequently beta decays to Cesium-135 then to Barium-135. The half-lives are shown in BLUE below the line.


Te135  ======>   I135  ======>  Xe135=======>  Cs135  =======>   Ba135 
<0.5 min               6.7 hr         9.2 hr        2 x 106 yr

How it destroy?
It has two ways to destroy:
  1. By its own radioactivity decay ( half-life 9.169 hours)
  2. By neutron absorption to Xe136
From the observation, it take time to produced and also take a long time to destroy...ermmmmm???What it means that?you think???
Opsss...I got to go. I hope this simple info will give all some knowledge...I will update more later...adiosss! :)
