How many types of atoms can be found in a in a single element?

Answer 1

A pure element contains one sort of atoms, and all the elements have the same number of protons (which define the element). But the atoms can have different masses, so called "isotopes" (see link). Thus, chemically there is only one kind of atoms in a pure element, but there can be several physically different kinds of nuclei in a pure element.

Answer 2

All of the atoms of an element have the same atomic number but may have different numbers of neutrons. Atoms of the same element with different numbers of neutrons are called isotopes. The number of isotopes varies from element to element.

Answer 3

there are 100 distinct forms but 90are found nature

pure gold it only contains only gold atoms and like nitrogen

Answer 4

one
