What is the mass number of ca 41?
It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope Ca-41 (Calcium, atomic number Z = 20, mass number A = 41).
How many neutrons does potassium 41 have?
Potassium-41 – It has 19 protons and atomic mass is 41. Hence, number of neutrons is 41 – 19 which is 22.
Is CA 41 radioactive?
Calcium also has a cosmogenic isotope, radioactive Ca-41, with a half-life of 102,000 years. The most stable of the artificial radioisotopes is Ca-45, with a half-life of 163 days.
Is Ca radioactive?
Calcium has six stable isotopes, two of which occur in nature: stable 40Ca and radioactive 41Ca with a half-life = 106 years. 97% of the element is in the form of 40Ca.
How many energy levels does calcium CA have?
These are in four energy levels (1 though 4) and it has the following electron configuration. The valence electrons for calcium are 2, 8, and 4, depending on the configuration of its electronic orbitals.
How many neutrons does chlorine have?
Every chlorine atom has 17 protons in its nucleus. Not all atoms of chlorine have the same number of neutrons, however. Some atoms of chlorine have 18 neutrons in their nuclei. Other atoms of chlorine may have 20 neutrons in the nucleus.
What is calcium 41 used for?
The rare, long-lived radiotracer, 41Ca, measured by accelerator mass spectrometry in the urine or serum following incorporation into the bone provides an ultra-sensitive tool to assess changes in bone calcium balance in response to an intervention.
How do U find neutrons?
To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.

Do most chlorine atoms contain 18 neutrons or 20 neutrons?
An element with 17 protons will always be chlorine. However an element’s mass numbers can vary, which means that it can have different numbers of neutrons. So although chlorine has a mass number of 35 which means it has 18 neutrons, it can also have a mass number of 37, which means it has 20 neutrons.
How do you find the neutrons of potassium?
It is the number under the element symbol. For potassium it is about 39. This means that the atomic weight is 39 for both protons and neutrons. Since we know that the number of protons is 19 we can calculate the number of neutrons (39 19) as 20.
Is CA 41 an isotope?
Calcium-41 (41Ca) is a rare long-lived radio-isotope of Calcium. Calcium-41 is called a cosmogenic nuclide, because it is created by energetic cosmic rays impacting matter in a fission reaction, called spallation.
Is calcium 40 stable or unstable?
Calcium 40 Carbonate (Calcium-40) is a stable (non-radioactive) isotope of Calcium. It is both naturally occurring and produced by fission.
