Examples of Isotopes

We explain that what are examples of isotopes? The isotopes are atoms of the same chemical element but have additional neutrons . Neutrons are subatomic particles that have no charge , so if they are left over, they do not modify the electrical balance of the atom. In isotopes, these give the atom a greater atomic mass (A), a property that is calculated with protons and neutrons. The atomic number (Z) remains the same because it is determined by the electrons. what are examples of isotopes

The same element can have several isotopes at the same time. In fact, most of them have more than one isotope. Only 21 in the periodic table have a single isotope . This will depend on several factors, including: the natural state of the atom and the conditions it is under. For the same reason, isotopes are classified into two categories: stable and unstable or radioactive . The characteristics of each are explained below.The stable isotopes are atoms of the same element that have extra neutrons but need not give off energy or particles to remain in balance. Just as they are, they are able to preserve their properties. In contrast, radioactive or unstable isotopes are those that tend to release an amount of energy or particles to achieve stability; decompose as a response to a mass overload.The radioactive isotopes are altered over time, emitting radiation in the form of alpha rays (helium nuclei), beta rays (electrons or positrons energy and speed) or gamma (high frequency energy of the electromagnetic spectrum). This phenomenon, called radioactive decay , is very useful for scientific work, for example in the branch of archeology; carbon-14 helps to calculate the age of traces found, based on their half-life .The half – life is the parameter indicating the time it takes to disintegrate half of the mass of a radioactive isotope. Some of the radioactive isotopes are not found in nature but are created by mankind in controlled environments such as laboratories. In the same way, the heaviest chemical elements have been created, with an atomic number greater than 110. Several of these are used in medicine for the detection of various types of cancer. what are examples of isotopes

To express the isotopes, the element symbol is placed, and to its left the values ​​of the atomic mass (A) and the atomic number (Z). One up and one down, as follows:

A E

Where: what are examples of isotopes

  • E: element symbol
  • A: atomic mass of the element
  • Z: atomic number of the element

For example, for hydrogen isotopes:

  • Protium: 1 H
  • Deuterium: 2 H
  • Tritium: 3 H
Some isotopes are used to produce nuclear energySome isotopes are used to produce nuclear energy.
