Defining Iodine-129

Iodine-129 is an isotope of iodine with an atomic number of 53 and a mass number of 129. This means it has 53 protons and 76 neutrons in its nucleus. The symbol for iodine-129 is written as ¹²⁹I.

Determining the Neutron Count

The number of neutrons in an atom’s nucleus can be calculated by subtracting the atomic number from the mass number. For iodine-129, this calculation is as follows:

Neutron count = Mass number - Atomic number
Neutron count = 129 - 53
Neutron count = 76

Comparison with Iodine-127

Iodine-129 is one of the two stable isotopes of iodine, along with iodine-127. Both isotopes have similar chemical properties, but they differ in their neutron count. Iodine-127 has 74 neutrons, while iodine-129 has 76. This difference in neutron count affects the isotopes’ stability and applications.

Stability and Uses of Iodine-129

Iodine-129 has a very long half-life of 15.7 million years, making it a stable isotope. This stability makes iodine-129 suitable for use in geological studies and as a tracer in environmental monitoring. It can also be used in medical applications, such as diagnostic imaging and radiotherapy.

Iodine-129 is an important isotope with a range of applications. Its 76 neutrons contribute to its stability and usefulness in various fields. Understanding the number of neutrons in iodine-129 provides valuable insights into the behavior and applications of this essential element.
