Go to the Periodic Table and look up the atomic number of iron (Fe). The atomic number of iron is equal to the number of protons in iron. Mass number is the number of protons plus the number of neutrons so add up the two values.

What is the number of neutrons of californium?
For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 98
What is the symbol and atomic number for an isotope with an mass number of 5 containing 10 neutrons?
The symbol for the isotope would be B and the atomic number would be 5, as the mass number is the sum of the protons and neutrons in the nucleus, so in this case: 5 protons + 10 neutrons = mass number 15.
What is the number of neutrons in polonium?
Depending on the isotope. Number of neutrons = Atomic mass of the isotope - 84
How many neutrons does technetium haave?
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
What is the mass number of an oxygen isotope that has nine neutrons?
The mass number of an isotope is the sum of its protons and neutrons. For oxygen, which has 8 protons, an isotope with nine neutrons would have a mass number of 8 (protons) + 9 (neutrons) = 17. Therefore, the mass number of this oxygen isotope is 17. This isotope is known as oxygen-17.
What isotope has 25 protons 25 electrons and 31 neutrons?
The isotope with 25 protons and 31 neutrons is Manganese-56. It has an atomic number of 25 (protons) and a mass number of 56 (protons + neutrons), which gives it 31 neutrons.
What is the symbol and atomic number for an isotope with an mass number of 191 containing 115 neutrons?
This an isotope of osmium, osmium-191. The symbol is 19176Os.
How many protons neutrons and electrons are in the isotope 52Mn?
The symbol Mn indicates a manganese atom, which always has 25 protons. The electroneutrality required for any atom requires the presence of 25 electrons to balance the electrical charge of the 25 protons. The mass number, 52 in this instances, is the sum of the numbers of protons and neutrons. Therefore, the number of neutrons in the isotope is 52 - 25 or 27.
How many neutrons are in the nucleus of an atom with an atomic number of 25?
The number of neutrons in the nucleus of an atom varies for each isotope of the element. Atomic number 25 means the atom contains 25 Protons, and it is the element Manganese (Mn). Manganese has 4 isotopes 52Mn, 53Mn, 54Mn & 55Mn. Take the number of protons (always 25 with Mn) from the isotope number and you will have the number of Neutrons in the nucleus. eg 55Mn will have 30 Neutrons.
