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.


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.


How many protons electrons and neutrons are there in a iron atom?

An iron atom has 26 protons, 26 electrons, and typically 30 neutrons.


What is the number of neutrons and protons in 52Fe?

Iron-52 (52Fe) has 26 protons and 26 neutrons. This is because the number following the element's symbol represents the total number of protons and neutrons in the nucleus.


How many neutrons and electrons are in iron?

An iron atom typically has 26 electrons and varying numbers of neutrons, depending on the isotope. The most common isotope, iron-56, has 30 neutrons.


What is the total number of nuetrons in an atom of iron-57?

In iron, there are 30 neutrons.


How do you find neutrons and protons in an ion element for iron?

the protons will be the atomic number, in this case 26. The neutrons depends on which isotope. The most common isotope is iron-56, so that will have 30 neutrons. If the element is written in symbolic notation, the number on the top, minus the number on the bottom is the number of neutrons.


How many neutrons does iron have?

It varies. Iron is element 26 with a relative atomic mass of 55.85That means that the naturally occurring isotopes must have a range of neutrons.92% of iron atoms have 30 neutrons, 8% have 28 neutrons; 2% have 31 neutrons and there is a small percentage


What is the mass number of an iron isotope with 26 protons 31 neutrons ans 24 electrons?

The mass number of an atom is the sum of its protons and neutrons. In this case, the iron isotope has 26 protons and 31 neutrons, so the mass number would be 26 + 31 = 57.


How many neutrons does iron 60 have?

The atomic number of an isotope is the same as the element - so Iron-59 would have an atomic number the same as Iron - or 26.Iron-59 specifically isa radioisotope of iron having a half-life of 45 days; used in ferrokinetics tests to determine the rate at which iron is cleared from the plasma and incorporated in red cells. Symbol 59Fe.


Why is atomic mass an average number?

The type of element an atom belongs to is determined by the number of protons in the nucleus. Iron, for example, always has 26 protons. The number of neutrons can vary. In naturally occurring iron there are four stable isotopes iron-54 (5.82 percent) 28 neutrons iron-56 (91.66 percent) 30 neutrons iron-57 (2.19 percent) 31 neutrons iron-58 (0.33 percent) 32 neutrons When doing calculations it is assumed the iron is close to this mixture and so the atomic mass will be calculated as the average weight of an iron atom.


How much newtrons are in iron?

How many neutrons, not how much newtrons. Iron's atomic number is 26, so it has 26 protons; its atomic mass is approximately 56, which equals the number of protons and neutrons. 56 - 26 = 20 neutrons. While there are isotopes of iron with more or fewer neutrons, this is likely the answer you're expected to provide. If not, see Wikipedia "isotopes of iron".
