none, nothing has an exact Atomic Mass, although because you are likely just in high school the answer you are expected to give is N, or Nitrogen
In order to find the number of neutrons in the atoms of an element, you must specify the isotope that you are interested in. Isotopes are specified according to their mass number. For example carbon-12 is the isotope of carbon that has a mass number of 12, and carbon-14 is the isotope of carbon that has a mass number of 14. All atoms of the same element, regardless of mass number, have the same number of protons, which is the element's atomic number. To determine the number of neutrons in an isotope, you subtract the atomic number from the mass number. For example, the atomic number of carbon is 6, which means that all carbon atoms contain 6 protons in their nuclei. So, to find the number of neutrons in a carbon-12 atom, subtract 6 from 12, and you get 6 neutrons in the atoms of carbon-12. To find the number of neutrons in a carbon-14 atom, subtract 6 from 14, and you get 8 neutrons in the atoms of carbon-14.
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14
The mass number of an isotope of an element is defined as the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope. The atomic number is defined as the number of protons only in the nucleus. Therefore, an atom with an atomic number of 6 has 6 protons in its nucleus.

A carbon atom with a mass number of 14 and atomic number of 6 will have 8 neutrons, calculated by subtracting the atomic number from the mass number. The mass number represents the sum of protons and neutrons in the nucleus of an atom, and the atomic number indicates the number of protons, which in this case would be 6 for carbon.
Carbon is a non metal element. Atomic mass number of it is 12.
Nitrogen has a gram atomic mass of 14.0067, an atomic number of 7, and the chemical symbol N.
Nitrogen is a non metal element. Atomic mass of it is 64.
Different isotopes of the same element have different numbers of neutrons but the same number of protons. The sum of the protons and neutrons is called the mass number. If you know the mass number and the number of protons (which is the atomic number), then you simply subtract the protons (or atomic number) from the mass number and the result is the number of neutrons. Example: Carbon-14 has a mass number of 14. Carbon's atomic number (and number of protons) is 6. So, 14 - 6 = 8 neutrons.
The isotope carbon 14: Atomic number = number of protons = number of electrons = 6 Atomic mass: 14,003241
The atomic weight is14.00674
Silicon is a non metal element. Atomic mass number of it is 28.
Nitrogen is a non metal element. Atomic mass number of it is 14.
In order to find the number of neutrons in the atoms of an element, you must specify the isotope that you are interested in. Isotopes are specified according to their mass number. For example carbon-12 is the isotope of carbon that has a mass number of 12, and carbon-14 is the isotope of carbon that has a mass number of 14. All atoms of the same element, regardless of mass number, have the same number of protons, which is the element's atomic number. To determine the number of neutrons in an isotope, you subtract the atomic number from the mass number. For example, the atomic number of carbon is 6, which means that all carbon atoms contain 6 protons in their nuclei. So, to find the number of neutrons in a carbon-12 atom, subtract 6 from 12, and you get 6 neutrons in the atoms of carbon-12. To find the number of neutrons in a carbon-14 atom, subtract 6 from 14, and you get 8 neutrons in the atoms of carbon-14.
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.
The atomic mass number A is the total number of protons and neutrons in an atom's nucleus. For nitrogen (N), the atomic number (number of protons) is 7. If it has 7 neutrons (designated as "7n"), then the atomic mass number A would be 14 (7 protons + 7 neutrons).
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14
