What is the isotope notation for cobalt?
symbol Co
Cobalt is a chemical element with symbol Co and atomic number 27.
How do you write isotope notation?
To write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol.
Why is Cobalt 60 no longer used?
Because it decays by gamma radiation, external exposure to Co-60 can increase cancer risk. Most Co-60 that is ingested is excreted in feces; however, a small amount is absorbed by the liver, kidneys and bones.
What are the dangers of cobalt 60?
Because it decays by gamma radiation, external exposure to large sources of Co-60 can cause skin burns, acute radiation sickness, or death. Most Co-60 that is ingested is excreted in the feces; however, a small amount is absorbed by the liver, kidneys, and bones.
Is P 37 A stable isotope?
Although phosphorus (15P) has 23 isotopes from 25P to 47P, only 31P is stable; as such, phosphorus is considered a monoisotopic element. The least stable is 25P with a half-life shorter than 30 nanoseconds. …
What element has the most isotopes?
The elements with the most isotopes are cesium and xenon with 36 known isotopes.
What are the two forms of isotope notation?
Isotope Notation Isotopes can also be defined in standard, or “AZE”, notation where A is the mass number, Z is the atomic number, and E is the element symbol. The mass number “A” is indicated with a superscript to the left of the chemical symbol “E” while the atomic number “Z” is indicated with a subscript.
What are the two types of isotope notation?
Most commonly, they are specified by the name or symbol of the particular element, immediately following by a hyphen and the mass number (e.g., carbon-14 or C-14). Isotopes can also be defined in standard, or “AZE”, notation where A is the mass number, Z is the atomic number, and E is the element symbol.
How is the stable isotope cobalt-60 produced?
It is produced by irradiating the stable isotope cobalt-59 with neutrons in a nuclear reactor. Cobalt-60 is used in the inspection of materials to reveal internal structure, flaws, or foreign objects and in the sterilization of food.
Is there a Britannica page for Cobalt 60?
THIS IS A DIRECTORY PAGE. Britannica does not currently have an article on this topic. In cobalt processing: Cobalt-60 A radioactive form of cobalt, cobalt-60, prepared by exposing cobalt to the radiations of an atomic pile, is useful in industry and medical science.
What can Cobalt 60 be used for in medical use?
In cobalt processing: Cobalt-60 A radioactive form of cobalt, cobalt-60, prepared by exposing cobalt to the radiations of an atomic pile, is useful in industry and medical science. Cobalt-60 is used in place of X-rays or radium in the inspection of materials to reveal internal structure, flaws, or….
What are the mass and neutron numbers of cobalt?
The chemical symbol for Cobalt is Co. Mass numbers of typical isotopes of Cobalt are 59. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.
