【 】How Many Neutrons Does Iron(Fe) Have?||Number of Neutrons in Iron(Fe)

Iron has 30 neutrons for this isotope.

Explanation:

Hello, chemistry lover! today we are going to help you to find out  how many neutrons iron   have in just 3 steps.

To find out the number of neutrons  for iron,we have to have knowledge about atomic number,atomic mass,mass number of iron
.Click picture to see clearly.

                    Step-1:


●The atomic number of iron is the number of protons in iron's nucleus.


●The atomic mass of iron is the average number of  protons plus neutrons of all the isotopes of iron.


●The masss number of iron is the number of protons plus neutrons of a specific isotope of iron.

                    Step-2:

We need to convert atomic mass of iron to mass number of  iron by rounding if necessary (In case of fraction) .

From periodic table,


  ●Atomic number of iron  is 26.

●Atomic mass of  iron is 55.85

●To find out mass number,we need to round 55.85 to a whole number.So,by rounding,we are getting mass number  of iron.The mass number of iron is 56.




                    Step-3:

By the difference between mass number and atomic number of iron,we get the number of neutrons in iron.


●Number of neutrons=56-26=30

In another way,

●Mass number=Protons +Neutrons

Or,56 =26 +Neutrons

Or,56-26=Neutrons

Therefore,
Neutrons=30




Therefore,the number of neutrons in iron is 30 here for this isotope.Remember that neutrons are present in the nucleous of iron and it's charge is zero.

●Number of protons in iron is 26.Protons are present in the nucleus of iron.



● Number of electrons in iron is 26.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of iron.
