Solution :-

Let the total no. electrons present in \(A^{3+}\) be x. 

Now, total no. neutrons in it = x + 30.4% of x = 1.304 x

Since the ion has a charge of +3 , no. electrons in neutral atom = x + 3

Therefore, no. protons in neutral atom = x + 3

The Mass number of the ion is 56 (Given)

Therefore, (x+3) + (1.304x) = 56

2.304x = 53

\(x=\dfrac{53}{2.304}\)

X = 23

Therefore, no. protons = x + 3 = 23 + 3 = 26

The ion is \(_{26}^{56}\textrm{Fe}^{3+}\)
