Aneutral atom of iron has a mass number of 56 and an atomic number of 26. how many protons, electrons and neutrons are in this atom? explain how you determine each number.

So here its given ..
mass no. = 56
and atomic no. = 26

=> in an atom there is an equal number of electrons and protons ...(e=p)..
=> also atomic number is the number of the electrons or protons ..
=> so here we got the no. of electrons and protons ..which is 26 ..
=> to find the number of neutrons in an atom , subtract atomic number from the mass number..i.e, 56 - 26 = 30 ...

=> so  there are 26 electrons , 26 protons and 30 neutrons in the given atom ...

Hope it helps !!!

Idon't know hope someone you
