Xenon ( Xe ) :
Define: Xenon is gas place in zero gas group .it is place in between Krypton and radon gas .xenon gives inert atmosphere to the other elements . It is non toxic in nature but it’s compound is highly toxic in nature because it’s act as oxidising agent. It is found in trace amount on the earth surface. Mainly 0.08 % present on earth. When xenon is burning it emits blue light
