What is the most abundant isotope of cobalt?
59Co
The isotopes of cobalt range in atomic weight from 50 amu (50Co) to 73 amu (73Co). The primary decay mode before the most abundant stable isotope, 59Co, is electron capture and the primary mode after is beta decay.

What is the percent abundance of lead?
Lead has four stable isotopes; their relative abundances are lead-204, 1.48 percent; lead-206, 23.6 percent; lead-207, 22.6 percent; and lead-208, 52.3 percent.
Is cobalt-60 an isotope?
Cobalt-60 is an isotope that emits gamma rays essential to the medical community for cancer treatments, as well as sterilization of medical devices. Sterilization Cobalt-60 is the first and most widely used type of Cobalt-60.
How abundant is cobalt-60?

Where does 60 percent of the world’s cobalt originate?
comes from Congo. Cobalt is mined all over the world, but 60 percent comes from Congo.
Is cobalt-60 rare?
Though relatively rare, exposure has also occurred by accidental mishandling of a source at a metal recycling facility or steel mill. Most exposure to Co-60 takes place intentionally during medical tests and treatments.
Why is cobalt-60 unstable?
One of its synthetic isotopes, Cobalt-60 (Co-60), has an extra neutron in its nucleus that makes it unstable. As it breaks down, Co-60 emits high energy, “ionizing” radiation that can break molecular bonds.
Is cobalt-60 still used?
Co-60 is used medically for radiation therapy as implants and as an external source of radiation exposure. It is used industrially in leveling gauges and to x-ray welding seams and other structural elements to detect flaws. Co-60 also is used for food irradiation, a sterilization process.
How do you find percent abundance?
How do you calculate the percentage of abundance based on mass? Calculate the average atomic mass using the atomic masses of each isotope and their percent abundances. Divide each percent abundance by 100 to convert it to decimal form. Multiply this value by the isotope’s atomic mass.
How do you find the abundance of a compound?
To determine the abundance of any compound, therefore, we simply sum the abundances of its compound ions.
How do you find the mass percent abundance of an element?
Change each percent abundance into decimal form by dividing by 100. Multiply this value by the atomic mass of that isotope. Add together for each isotope to get the average atomic mass.
What isotope is cobalt?
Naturally occurring cobalt (27Co) consists of a single stable isotope, 59Co. Twenty-eight radioisotopes have been characterized; the most stable are 60Co with a half-life of 5.2714 years, 57Co (271.8 days), 56Co (77.27 days), and 58Co (70.86 days).
What is the difference between cobalt-59 and cobalt-60?
Cobalt-60 and cobalt-59 are isotopes. This means that while they have the same number of protons (proton number determines the identity of the isotope), they have different mass numbers because they contain different numbers of neutrons.
What is meant by cobalt-60?
cobalt-60, radioactive isotope of cobalt used in industry and medicine. Cobalt-60 is the longest-lived radioactive isotope of cobalt, with a half-life of 5.27 years. It is produced by irradiating the stable isotope cobalt-59 with neutrons in a nuclear reactor.
Is there a limited supply of cobalt?
Cobalt, by nature, is a finite resource: There is only so much that exists in the world.
Is cobalt an earth abundant metal?
In this regard, abundant first-row transition metals, such as manganese, iron, cobalt, nickel, vanadium, or chrome play an important role due to their economic and ecological benefits. In this section, we highlight articles that explore the catalytic potential of earth-abundant metals in organic transformations.
Where is most of the cobalt in the world?
The Democratic Republic of the Congo
The Democratic Republic of the Congo has the largest cobalt reserves in the world, at some 3.5 million metric tons as of 2021. As the total global cobalt reserves amount to 7.6 million metric tons, this means that the DR Congo’s cobalt reserves account for nearly half of the world’s reserves of the metal.
What country produces 70% of the world’s cobalt?
The Democratic Republic of Congo (DRC) is by far the world’s largest producer of cobalt, accounting for roughly 70 percent of global production. The country has been the top producer of the metal for some time, and its output increased from 98,000 MT in 2020 to 120,000 MT in 2021.
How much cobalt is used in a Tesla battery?
Cobalt accounts for almost three percent of materials used in Tesla-made batteries.
