What Isotope Is Cobalt?

⁵⁹Co.
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 two isotopes of cobalt?

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 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.

Is cobalt a radioactive isotope?

Cobalt is similar to iron and nickel in its properties and can be magnetized like iron. The most common radioactive isotope.

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.

What is cobalt 2+ called?

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

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.

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.

What can carbon-14 be used for?

Archaeologists have long used carbon-14 dating (also known as radiocarbon dating) to estimate the age of certain objects. Traditional radiocarbon dating is applied to organic remains between 500 and 50,000 years old and exploits the fact that trace amounts of radioactive carbon are found in the natural environment.

Is cobalt used in drugs?

Cobalt is a versatile transition metal for drug development. The tunable physicochemical properties can be exploited by understanding the mechanism of bioactive cobalt complexes.

What type of element is cobalt?

transition metals
Cobalt is a lustrous very hard silvery metal belonging to a group called the “transition metals“. It is one of only 3 ferromagnetic transition elements along with iron and nickel.

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.

Is cobalt radioactive or stable?

Cobalt-59 is naturally occurring and is stable. Cobalt-50 through 58 and 60 through 75 are artificially produced and are radioactive.

Which element 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. When an isotope is unstable it will decay over time and eventually it will turn into another isotope or element. Unstable isotopes are considered radioactive.

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 is the most abundant isotope of an?

These include isotopes with atomic masses between 112 and 124 (except 113, 121 and 123). Of these isotopes, tin-120 is most common.

What is cobalt 3 called?

Cobaltic cation

Why is cobalt blue called that?

The name “Cobalt blue” comes from Middle High German kobolt = an underground goblin (cobalt was thought to be detrimental to silver ores).

What is cobalt?

cobalt (Co), chemical element, ferromagnetic metal of Group 9 (VIIIb) of the periodic table, used especially for heat-resistant and magnetic alloys.

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.

Is cobalt-60 a compound?

Structure for T3D4973: Cobalt-60
belongs to the class of inorganic compounds known as homogeneous transition metal compounds.
