Well, considering Nitrates are NOT elements, and can vary in amount of protons, they do not have a consistent atomic number.
Well for one reason is on the periodic table the transition metals such as copper, and the non metals such as sulfur are in the same family but not the same group their atomic number is slightly different due to the number of protons, and neutrons. Their atomic mass is quite similar to this is why they are virtually identical.
this elemnt has an atomic number that is double the atomic number of silicon?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
You subtract the atomic number from the mass number.
The atomic number is equal to the protons and electrons of an element.
Nitrogen is a none metal element. atomic number of it is 7.

The atomic number is the number of protons in an atom. It is also the big whole number in the block with the element on the periodic table. Sodium Nitrate is not a atom, it is a compound. The formula for sodium nitrate comes from the fact that sodium has a +1 charge and nitrate (NO3) has a -1 charge, so its NaNO3. I GUESS you could take the atomic number of sodium, nitrogen, and oxygen and add them all up.... 11 + 7 + 3(8)= 42 but that's not really the atomic number......did you misunderstand the question? Perhaps it is asking for the atomic mass? Then you would add up the masses from the periodic table in the same way.

Be(NO3)2
the answer is that it is called a atomic number.
The atomic number is equal to the number of the protons in the atomic nucleus.
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.

Subtract the atomic number from the atomic weight.
