Why is the atomic number of calcium 20?
The mass number of an isotope is the sum of the number of protons and neutrons in the atomic nucleus. The atomic number is the number of protons. The calcium-40 isotope has a mass number of 40 , and an atomic number of 20 , therefore it has 20 protons.
What is calcium 48 used for?
Since 48Ca is both practically stable and neutron-rich, it is a valuable starting material for the production of new nuclei in particle accelerators, both by fragmentation and by fusion reactions with other nuclei, for example in the discoveries of the heaviest five elements on the periodic table, from flerovium to …

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 is atomic mass Class 9?
Mathematically, mass of one atom of an element = atomic mass X (1/12th) of the mass of one atom of carbon. atomic mass = mass of one atom of an element / (1/12th) of the mass of one atom of carbon. Easy way to calculate atomic mass of oxygen atom.
What is the molecular weight of calcium?
