Question

. The atomic number of an element is 26 and mass number is 56. How many electrons and protons of an atom of this element has? How many neutrons does this atom has?

Answer 1

Answer:The 26 is the atomic number (which is the same for all iron atoms), while the 56 is the mass number of the isotope. To determine the number of neutrons in this isotope, we subtract 26 from 56: 56 − 26 = 30, so there are 30 neutrons in this atom.
