The atomic mass (rounded to the nearest whole number) is the number of nucleons - i.e. protons+neutrons. The atomic number is just the number of protons. So the difference between the two (mass minus number) tells you the number of neutrons.

If you know the atomic number and the mass number of an isotope how could you figure out the number of neutrons in its nucleus?

The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.

How do you calculate the number of neutrons an element has in its nucleus?

You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.


How do you find the neutrons that are in the nucleus?

Number of neutrons = Atomic mass of an isotope - Number of protons (Atomic number)


When you subtract the atomic number from the atomic mass of any element you get what?

Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.


Can the number of neutrons in the nucleus be calculated by subtracting the atomic number from the mass number?

Yes, the number of neutrons in the nucleus can be calculated by subtracting the atomic number from the mass number. The mass number represents the total number of protons and neutrons in the nucleus, so by subtracting the atomic number (number of protons), you can determine the number of neutrons.


Is atomic mass the amount of neutrons in the nucleus in the atom?

atomic mass = number of neutrons + number of protons.


The sum of protons and neutrons in the nucleus of an atom is the?

Atomic Mass. This can vary depending upon the number of neutrons in the nucleus. Whereupon it is known as an ISOTOPE. Do NOT confuse Atomic Mass , with Atomic Number(Z). The Atomic Number is an elements position in the Periodic Table, AND the number of PROTONS in the nucleus.


Mass number - atomic number?

The mass number represents the total number of protons and neutrons in the nucleus of an atom. The atomic number specifies the number of protons in the nucleus. The difference between the mass number and atomic number gives the number of neutrons in the nucleus.


How do you tell figure out the atomic mass?

Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.


The number of neutrons in the nucleus of an atom can be calculated by what?

The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.


How many neutrons are in the nucleus of magnesium?

The number of neutrons in the nucleus of an element can be calculated by subtracting the atomic number (which is the number of protons) from the atomic mass. For magnesium, the atomic number is 12, and the atomic mass is usually around 24-25. Therefore, the approximate number of neutrons in the nucleus of magnesium is 12-13.
