What Isotopes Does Cobalt Have?

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 are the three isotopes of cobalt?

Isotopes. Naturally occurring cobalt is composed of 1 stable isotope, ⁵⁹Co. 22 radioisotopes have been characterized with the most stable being ⁶⁰Co with a half-life of 5.2714 years, ⁵⁷Co with a half-life of 271.79 days, ⁵⁶Co with a half-life of 77.27 days, and ⁵⁸Co with a half life of 70.86 days.

What is the most abundant isotope of cobalt?

The isotopes of cobalt range in atomic weight from 50 u (⁵⁰Co) to 73 u (⁷³Co). The primary decay mode for isotopes with atomic mass unit values less than that of the most abundant stable isotope, ⁵⁹Co, is electron capture and the primary mode of decay for those of greater than 59 atomic mass units is beta decay.

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.

Does cobalt have a radioactive isotope?

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.

What is cobalt 2+ called?

Cobalt(2+) is a divalent metal cation, a cobalt cation and a monoatomic dication.

What are the 3 isotopes of an element?

If we talk about the element Hydrogen, it has three stable isotopes namely protium, deuterium, and tritium. These isotopes have the same number of protons but a different number of neutrons wherein protium has zero, deuterium has one and tritium has two.

Which metal has the most isotopes?

The elements with the most isotopes are cesium and xenon with 36 known isotopes. Some isotopes are stable and some are unstable.

What is isotope of cobalt used for?

What is it used for? 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 many naturally occurring isotopes of cobalt are there?

There are 30 isotopes and isomers of cobalt that are recognized.

What is U 238 used for?

Depleted uranium (uranium containing mostly U-238) can be used for radiation shielding or as projectiles in armor-piercing weapons. Where does it come from? U-235 and U-238 occur naturally in nearly all rock, soil, and water. U-238 is the most abundant form in the environment.

Which isotope has 60 neutrons?

Silver
Silver is the second element in the eleventh column of the periodic table. It is classified as a transitional metal. Silver atoms have 47 electrons and 47 protons with 60 neutrons in the most abundant isotope.

How do you write cobalt-60 as an isotope?

The most common radioactive isotope. For example, uranium has thirty-seven different isotopes, including uranium-235 and uranium-238. of cobalt is cobalt-60 (Co-60).

Why is cobalt-60 so radioactive?

Cobalt-60 decays by beta and gamma emission to non-radioactive nickel. Most of the radiation from the decay of cobalt- 60 is in the form of gamma emissions; some is in the form of beta particles. Beta particles are generally absorbed in the skin and do not pass through the entire body.

What is the most radioactive thing on earth?

radium
The radioactivity of radium then must be enormous. This substance is the most radioactive natural element, a million times more so than uranium.

How do you determine isotopes?

Subtract the atomic number (the number of protons) from the rounded atomic weight. This gives you the number of neutrons in the most common isotope. Use the interactive periodic table at The Berkeley Laboratory Isotopes Project to find what other isotopes of that element exist.

What colour is cobalt 3+?

In fact the hexaamminecobalt(III) ion is yellow! What you see is a mixture of this ion and various other cobalt(III) ions involving ligand exchange reactions with both water molecules and negative ions present in the solution.

What is cobalt made of?

Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth’s crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron.

Is cobalt a copper?

Cobalt (Co) is a hard and lustrous metal and is mainly obtained as a by product of nickel and copper mining activities. Cobalt is used in the preparation of magnetic, wear-resistant, and high-strength alloys.
