What the atomic number of F plus the atomic number of Na equals equals the atomic number of this element?
At No(F) + At No(Na) = 20.At No of Calcium = 20.
What is the atomic number for calcium?
The most common calcium isotope, calcium-40, has 20 neutrons.
Atomic number for argon?
Argon is a gas. atomic number of it is 18.
Calcium has an atomic mass of an atomic number of 20 so the number of neutrons must be?
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass. For calcium with an atomic number of 20, if the atomic mass is 40, then the number of neutrons would be 40 - 20 = 20 neutrons.
