IsotopeIsotopes
They are called as isotopes of the given element.
Those are different isotopes of the same element. Different isotopes of the same element have the same number of protons, but a different number of neutrons. There are a little over 100 known elements, but over 3000 different known isotopes.
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
Presumably you mean radio-isotopes? These are produced usually in small reactors built for the purpose and possibly for other experimental purposes. Short lived isotopes are the most useful for medical tracer purposes as the activity soon dies away. Longer lived and higher energy ones are useful for radioactive treatment of tumors and other conditions. This question is not really relevant to Nuclear Energy and I will transfer it to Medical questions.
An atom or element that have different masses are known as isotopes.
leucite
The names are assigned to them based on their properties.
The periodic table is based on an element's number of atoms. The elements are arranged from least to most number of atoms.
'ISOTOPES'. The definitive statement is ' Isotopes of the same element have a different number of neutrons'. NB Do NOT confuse with 'Allotropes' . Allotropes of the same element exhibit different physical characteristics. The elements Sulphur and Phosphorus are the two classic examples of allotropes.
