Selenium is
a chemical element with symbol Se and atomic
number *4. It is a nonmetal with properties that are intermediate
between those of its periodic table column-adjacent chalcogen
elements sulfur and tellurium. It rarely occurs in its elemental
state in nature, or as pure ore compounds.
Selenium (Se) has six naturally
occurring isotopes, five of which are stable:*4Se,*6Se,*7Se,*8Se,
and*0Se. The last three also occur as fission
products, along with*9Se
which has a half-life of **7,**0 years and*2Se
which has a very long half-life (~*0*0 years, decaying via double beta decay
to*2Kr) and for practical purposes can be
considered to be stable. *3 other unstable isotopes have been
characterized. Standard atomic mass: *8.*6(3) u
