Atomic number is a property of an atom (An Element) and not a chemical compound. Sodium chloride is a compound and thus it can not have any atomic number.
Atomic number is the number of protons present in the nucleus of the atom of an element. e.g. Carbon has six protons in its nucleus, therefore its atomic number is six. However, sodium chloride has two different elements as its constituents and therefore one can not determine its atomic number.
The most common calcium isotope, calcium-40, has 20 neutrons.
At No(F) + At No(Na) = 20.At No of Calcium = 20.
If the atomic number of Element D is 20, then Element D is calcium (Ca). The atomic number of calcium is 20, so R would also have an atomic number of 20. This means that R would also be calcium (Ca).
Calcium sulfide has the chemical formula CaS.
The chemical formula for Calcium Sulfate is CaSO4
The atomic number of calcium is 20.
The most common calcium isotope, calcium-40, has 20 neutrons.
Probably sulfur, not sulphate. The atomic number of sulfur is 16.
The atomic number of calcium is 20.
The atomic number of Calcium is 20.
Calcium is a metal element. atomic number of it is 20.
Calcium is a meta element. Atomic number of it is 20.
The atomic number of calcium is 20. The atomic number tells you the number of protons in the nucleus of a calcium atom, which also corresponds to the number of electrons in a neutral calcium atom.
Calcium is a metal element. Atomic mass of it is 40.
Calcium is a metal element. Atomic number of it is 20.
The symbol for calcium is Ca and its atomic number is 20.
Calcium's atomice weight is 40.078 amu (atomic mass units).
