What is the structural difference between Cobalt-60 and the other Cobalts?
A number following an element, such as cobalt-60, tells us that a specific isomer of that element is being referenced. Isotopes are atoms of the same element that have a different number of neutrons in the nucleus. All cobalt atoms will have the same amount of protons, 27, because that is what makes it cobalt, however they can have a different amount of neutrons. The mass number is the number following the element's name and it tells us the total of both protons and neutrons in the nucleus. By subtracting the 27 protons in cobalt from the mass number of the isotope we find that cobalt-60 has 33 neutrons while cobalt-59 has 32 neutrons. This means that the structural difference between cobalt-60 and other isotopes of cobalt is the number of neutrons in the nucleus. Another fun fact: Cobalt-60 is the radioactive isotope commonly used in radiation therapy for cancer.
The atomic masses of two isotopes of cobalt are 59 and 60 what is the number of protons and neutrons in each?
For the isotope with an atomic mass of 59, which is cobalt-59, it has 27 protons and 32 neutrons. For cobalt-60, it has 27 protons and 33 neutrons. This is because the atomic mass includes both protons and neutrons, so subtracting the atomic number (equal to the number of protons) from the atomic mass gives the number of neutrons.
What is cobalts atomic number?
A typical atom of cobalt contains 32 neutrons. Cobalt's atomic number is 27, so that's 27 protons. Its average atomic mass is about 59, so 59-27=32. Note: different isotopes of cobalt will have either more or less neutrons than 32, but most likely, cobalt's most abundant isotope has 32. The atomic mass value on the periodic table, which is 58.933, is a weighted average of all cobalt's isotopes.
How many types of elements are in cobalt(II) carbonate CoCO3?
There are three(3) elements in cobalt carbonate. They are Cobalt Carbon Oxygen
Is cobalt an element or compound?
elementCobalt is an element, and is a transition metal with atomic number 27.
How many neutron does cobalt have?
Most elements have different isotopes, with different numbers of neutrons. Once source to get more information about the cobalt isotopes is the Wikipedia article on Cobalt - look for the section on isotopes.
How many neutrons are in cobalt?
Stable cobalt has 32 neutrons, but all the produced isotopes range from 20 to 48 neutrons
The uses of radio isotopes of cobalt-59?
killer to any one
Benefits of nuclear waste?
From nuclear wastes can be extracted plutonium, uranium, useful isotopes of cobalt, strontium, prometium, technetium and many other.
What are 2 radioactive isotopes that make them useful?
Two examples are: carbon-14 and cobalt-60.
What is the average atomic mass for cobalt?
The average atomic mass for cobalt is approximately 58.93 atomic mass units. It is calculated by taking into account the different isotopes of cobalt and their relative abundance in nature.
What is the structural difference between Cobalt-60 and the other Cobalts?

What are short-lived isotopes?
Short-lived isotopes are isotopes with relatively short half-lives. Note that short-lived is a relative term, and that means you need to make some kind of comparison to use the term correctly. Let's look at one example using cobalt, which has only one stable isotope, cobalt-59.We make cobalt-60 by lowering a fixed amount of cobalt-59 into an operating nuclear reactor. It will bathe in the neutron flux there to become activated (neutron activation). The cobalt-59 absorbs a neutron and has been activated to become cobalt-60, which is an unstable isotope of cobalt. That means it is radioactive, and it has a half-life of 5.2714 years. If we look at another isotope, cobalt-58, we find it has a half life of 7.86 days. It's a short-lived isotope of cobalt, compared to cobalt-60. Need another example? Then let's do one more.In the case of rubidium, the isotope rubidium-85 is the only stable isotope of this metal. Rubidium-87, on the other hand, has a half-life of 4.88x1010 years, which is longer than the estimated age of the universe. (Wow!) The isotopes rubidium-83 and rubidium-84 have half-lives of 86.2 days and 32.9 days, respectively. These two isotopes are short-lived isotopes of rubidium, at least compared to the long-lived rubidium-87 isotope.There are many isotopes of elements that have been synthesized in the nuclear physics labs, and a lot of them have half-lives of less than one second. The term short-lived isotope is a relative term, and it should be used with that idea in mind. The difference between the two (or more) compared isotopes can be smaller, as in the case of cobalt, or larger, as we showed in rubidium. That difference doesn't have to be specific either, so remember that as well.We'll depart with the idea that the term "short-lived isotope" is often encountered in medical imaging. The short-lived isotopes referred to usually have half-lives of days or even hours, and are synthesized shortly before use (because they don't last long).
What are two radioactive isotopes that are used to irradiate food?
Cobalt-60 and Cesium-137 are two radioactive isotopes commonly used to irradiate food for preservation purposes. They help eliminate harmful bacteria and pests, extending the shelf life of food products.
How much cobalt will remain in the rock after 21.2 years?
This seems to refer to radioactive decay. The answer would depend on the isotope of cobalt used! For example, cobalt-59 is stable, so in this case, all of the original cobalt would remain.For more information, check the Wikipedia article entitled "Isotopes of cobalt".
