What is atomic number and where can you find an element's atomic number?
The atomic number is the number of protons in the element. For example calcium has 20 protons, so that means it has an atomic number of 20. You can find the element's number on the periodic table; its usually the number on top of the element's symbol
If the atomic number of Element D is 20 then what is the atomic number of R?
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).

What is the atomic number and the mass number of an element with 20 atomic number and 23 mass number?
The element with atomic number 20 is calcium. The mass number 23 indicates the total number of protons and neutrons in the nucleus of the atom. Since the mass number is 23 and the atomic number is 20, the number of neutrons in this calcium atom would be 3 (23 - 20).
