Mattauch isobar rule
The
Mattauch isobar rule
, formulated by
Josef Mattauch
in 1934, states that if two adjacent
elements
on the
periodic table
have
isotopes
of the same
mass number
, one of these
isotopes
must be
radioactive
. Two
nuclides
that have the same mass number (
isobars
) can both be stable only if their
atomic numbers
differ by more than one. However, this rule cannot make predictions on the
half-lives
of these
radioisotopes
.
