Question

An ion with mass number 52 contains 3 unit of positive charge and 30.4%

Answer 1

Let the number of electrons in ion = x

Number of neutrons = x+0.304x = 1.304x

Number of electrons in neutral atom = x+3

Number of protons in neutral atom = x+3

Mass number = 56

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

X = 23

Number of protons = x+3 = 26

Symbol of ions = Fe3+
