 Isotopes
 returns a list of the isotopes of an element

 Calling Sequence Isotopes(element)

Parameters

 element - name or string; name or symbol of the element

Description

 • The Isotopes command returns the isotopes of a given element.
 • The output is a list of the isotopes specified by an atomic symbol and subscript.
 • The subscript indicates the total number of protons and neutrons in an atom of the isotope.
 • Two isotopes of an element have the same number of electrons and protons but different numbers of neutrons.
