The atomic number of F (fluorine) is 9, Na (sodium) is 11. When you add them together, you get 20. The element with atomic number 20 is calcium (Ca).
The atomic number of F is 9, Na is 11, so F (9) + Na (11) = 20. The element with an atomic number of 20 is calcium (Ca).
No, sulfur-36 and argon-36 do not have the same atomic number. Sulfur-36 has an atomic number of 16, while argon-36 has an atomic number of 18.
it equals the atomic number of balls plus dick which is B^2*D^2
The atomic number of F is 9, Na is 11, so F (9) + Na (11) = 20. The element with an atomic number of 20 is calcium (Ca).
The atomic number of F is 9, the atomic number of Na is 11. Adding them together gives a sum of 20, which corresponds to the atomic number of Calcium (Ca).
The atomic number of F (fluorine) is 9, Na (sodium) is 11. When you add them together, you get 20. The element with atomic number 20 is calcium (Ca).
it is the total number of protons plus the total number of neutrons expressed in atomic mass units
Roughly, the number of neutrons. Note that the atomic mass is only approximately equal to the number of protons plus the number of neutrons - there is a relatively small discrepancy, due to the binding energy.
The atomic number of F (fluorine) is 9 and the atomic number of Na (sodium) is 11. Adding them together gives 20, which is the atomic number of calcium (Ca).
The atomic number is used to determine the order of the elements on the modern periodic table. The atomic number represents the number of protons in the nucleus of an atom, which defines the element. Elements are arranged on the periodic table in order of increasing atomic number.
Any number plus zero equals the original number. Any number times one equals the original number.
The atomic mass of an element is average of the number of protons in an atom plus the number of neutrons. For example, if you look at a periodic table of elements, Hydroge has the atomic mass of 1.0079.
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
