Heavy elements are the
general name for elements containing atomic numbers greater than 92.
Above these, elements with atomic numbers 112 and above are called
superheavy elements. The state that creates the atomic number is the
number of protons in the nucleus of the element.
Detailed Definition:
Heavy elements, which are
determined by the number of protons in the nucleus of the element
(this called atomic number) are elements with atomic number greater
than 92. One row above them there is superheavy elements with atomic
numbers greater than 112. The first artificially produced heavy and superheavy
elements were first produced during the Cyclotron experiments.
One
of the most important issues about heavy elements is the concept of
'island of stability'. This concept refers to the region in the table
of nucleides where elements with half-lives longer than some other
super heavy elements are found. However, it should be noted that we
are ona narrow time scale, from minutes to micro/nano seconds at
most. The term was first coined in 1998 with the discovery of the
super heavy element 114 (Flerovium).
‘’Although
the scientific community has assigned these heaviest elements to
their own spots on the periodic table, there is still a lot we don’t
know about them.’’
