Which is an isotope of calcium 41?
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….Calcium-41 (41Ca)
| half-life (λ) | 100,000y |
|---|---|
| Protons | 20 |

How many electrons does calcium 41?
Since a stable atom has a net charge of 0 , we must have 20 electrons.
Is calcium 40 and calcium 41 isotopes?

What is calcium 40 used for?
Uses and properties Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
What is the difference between calcium 40 and calcium 42?
Calcium-40 is theorized to actually be a radioactive isotope with an extremely long half-life (~1021 years) based on its internal structure. No one has ever detected a decay of a calcium-40 atom. Calcium-42 is a stable isotope containing 22 neutrons. 0.647% of natural calcium is calcium-42.
What does the 40 in calcium-40?
(physics) Tha major stable isotope of calcium, 4020Ca, having twenty protons and twenty neutrons; it amounts to almost 97% of the element in nature.
How are calcium isotopes used in clinical research?
Calcium: isotope data. Calcium isotopes (mainly Ca-42, Ca-44, Ca-46 and Ca-48) are used extensively in clinical research and mainly in nutritional studies. They are used to measure calcium absorption mainly in women and children. In adults, calcium deficiency is strongly related to increasing severity of osteoporosis.

How is calcium deficiency related to osteoporosis?
In adults, calcium deficiency is strongly related to increasing severity of osteoporosis. In children, calcium deficiency is primarily related to the development of rickets. Ca-48 has been used to bombard Pb and Bi targets in order to create super heavy elements.
