Overview of the isotopes of calcium

Isotopes of Calcium[edit]

Calcium (Ca) is a chemical element with the atomic number 20. It is a member of the alkaline earth metals in group 2 of the periodic table. Calcium has several isotopes, which are variants of the element that differ in the number of neutrons in their nuclei.

Stable Isotopes[edit]

Calcium has six naturally occurring isotopes: ⁴⁰Ca, ⁴²Ca, ⁴³Ca, ⁴⁴Ca, ⁴⁶Ca, and ⁴⁸Ca. Of these, ⁴⁰Ca is the most abundant, making up about 96.9% of natural calcium.

⁴⁰Ca: This is the most common isotope of calcium and is stable. It is used in various applications, including as a standard in mass spectrometry.
⁴²Ca: A stable isotope that makes up about 0.647% of natural calcium.
⁴³Ca: This stable isotope is used in NMR spectroscopy due to its nuclear spin.
⁴⁴Ca: Another stable isotope, comprising about 2.086% of natural calcium.
⁴⁶Ca: A rare stable isotope, making up only 0.004% of natural calcium.
⁴⁸Ca: This isotope is notable for being a double beta decay candidate and is used in neutrino experiments.

Radioactive Isotopes[edit]

Calcium also has several radioactive isotopes, which are not found naturally but can be produced in laboratories.

⁴¹Ca: This isotope is used in radiometric dating and has a half-life of about 100,000 years.
⁴⁵Ca: A radioactive isotope with a half-life of 162.7 days, used in biological research to study calcium metabolism.

Applications of Calcium Isotopes[edit]

Calcium isotopes have various applications in scientific research and industry. Stable isotopes like ⁴³Ca are used in NMR spectroscopy to study molecular structures. Radioactive isotopes such as ⁴⁵Ca are used in biological research to trace calcium pathways in organisms.
