Question

A ion with the mass number 56contain 3 units positive charge and 30.4% more neutrons than the electrons. Assign symbol.

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⁺
