varun · Answer

Let the number of electrons in ion=X no of protons or atomic number of element =X+3 no of neutrons in ion =X+30.4% of X =X+0.304X Atomic mass of element in sum of the element of neutrons and no of protons of the elememt,,thus 56=(X+3)+(1.304)X solving.X=3 hence atomic no of element is 23+3=26 threfore the element is IRON BEST OF LUCK spare me if the answer is wrong
