Text: An exclave is a portion of a state or territory geographically separated from the main part by surrounding alien territory (of one or more states). Many exclaves are also enclaves. Enclave is sometimes used improperly to denote a territory that is only partly surrounded by another state. Vatican City and San Marino, enclaved by Italy, and Lesotho, enclaved by South Africa, are the only completely enclaved states. Unlike an enclave, an exclave can be surrounded by several states. The Azerbaijani exclave of Nakhchivan is an example of an exclave.

Text: The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons. The number of nucleons (both protons and neutrons) in the nucleus is the atom's mass number, and each isotope of a given element has a different mass number.

Question: is it possible for an element to have different types of atoms?
