Calcium is a chemical element with the symbol Ca and atomic number As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its. There is evidence for minor isotope fractionation of calcium in Nature, causing Variations in n(44Ca)/n(40Ca) can be reported as δ44Ca values relative to the.
Atomic Weight of Calcium Commission on Isotopic Abundances and Atomic Weights
First of all, I think that your question has an error, as there is no way a calcium atom is 40 times greater than the mass of a carbon atom.
Oxford: Pergamon Press. It is sometimes interpreted as the expected range of the relative atomic mass values for the atoms of a given element from all terrestrial sources, with the various sources being taken from Earth. Reveal answer up. Appearance The description of the element in its natural form.

Calcium Element information, properties and uses Periodic Table
How do you calculate the relative atomic mass of an element. hydrogen H = 1. or ~1; calcium Ca = or ~; chlorine Cl = ~, copper Cu. The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope Thus, since the atomic mass of iron is amu, one mole of iron atoms would weigh grams. 20, Ca, Calcium,
