Answer:
Atomic number 26,atomic mass 26+30=56 dalton and net charge is 3+
Explanation:
The total number of proton present in an atom is known as the atomic number of that atom.From that point of view the atomic number of iron ion is 26.
The total number proton and neutrons present in the nucleus of an atom or ion is termed as atomic mass.From that point of view the the atomic mass of iron ion is 26+30=56 dalton
According to the given question iron ion contain 3 more protons than electrons as a result the iron ion will contain 3 unit positive charge.
