Mass number (of an isotope) is number of neutrons PLUS number of protons (this equals the atom number, which is 26 for element Fe) , so 28 + 26 = 54 is the mass number

How many neutrons are present in atom of iron 54?
An atom of iron with a mass number of 54 contains 30 neutrons. This can be determined by subtracting the atomic number (26) from the mass number (54), which gives the number of neutrons in the nucleus.
What is the mass number of an iron that has 29 neutrons?
The mass number of an iron is determined by the total number of protons and neutrons. Iron has an atomic number of 26, meaning it has 26 protons. If the iron atom has 29 neutrons, the mass number would be 26 (protons) + 29 (neutrons) = 55.
What is the sum of protons and neutrons in an atom?
Mass number!:)
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
What is the approximate mass of a neutral atom with 31 electrons and 38 neutrons?
The mass of an atom is primarily determined by the protons and neutrons it contains since electrons have negligible mass. With 38 neutrons and an atomic number of 31 (which corresponds to the number of protons), this atom is likely a neutral atom of gallium. The approximate mass of this neutral atom can be calculated using the atomic mass of gallium (around 69.7 g/mol).
What is the mass number of an iron isotope with 26 protons 31 neutrons ans 24 electrons?
Number of protons + neutrons = mass number 26 protons + 31 neutrons 57
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
Is the number of neutrons in an atom known as its mass number?
No, neutrons + protons = mass
Iron-56 mass number?
Iron is a metal element. Atomic mass of it is 56.
What is the total amount of protons and neutrons in an atom?
The total amount of protons and neutrons in an atom is its mass number.
What particle has 26 electrons 29 neutrons and 26 protrons?
The particle you are describing is an atom of iron. The number of protons in an atom determines its atomic number, which is 26 for iron. The sum of protons and neutrons gives the atomic mass number, which is 56 for this iron atom.
How is the number of neutrons in an atom found?
The number of neutrons in an atom can be found by subtracting the number of protons (which is the atomic number) from the mass number. The mass number is the sum of protons and neutrons in the nucleus of an atom.
