What is the most stable element?
There are some 90+ elements of the periodic table that occur naturally in the Universe, but of them all,
iron
is the most stable. If you fuse lighter elements together to get closer to iron, you gain energy; the same is true if you split heavier elements apart.
How do you know if a nucleus is stable?
The principal factor for determining whether a nucleus is stable is
the neutron to proton ratio
. Elements with (Z
What is the most stable isotope?
The element with the most stable isotopes is
tin
which has ten different stable isotopes. Many elements only exist in an unstable or radioactive form. All non-natural or man-made elements are radioactive isotopes.
