INTRODUCTION
Meitnerium is an extremely rare, unstable chemical element. The large number of particles in the nucleus makes the atom unstable and causes the atom to split apart into smaller components soon after it is created.
It was renamed from unnilennium to meitnerium in honour of Austrian Swedish physicist Lise Meitner, a pioneer in the field of nuclear fission (the splitting of atomic nuclei).

EXTRACTION
It is obtain by electrolysis of its fused salts or reducing its halides with calcium
OXIDATION STATES
+9,+8,+6,+4,+3,+1
MAJOR SOURCE
It is produced artificially by nuclear fusion
HALF LIFE
Meitnerium-266 = 0.0068 seconds, Meitnerium-268 = 0.14 seconds
ECONOMIC IMPORTANCE
* Due to its short life span, Little is known about the element, so therefore; it does not have any industrial use, presently.
