Chapter 1, Problem 57AE

Interpretation Introduction

Interpretation: For an element number of electron, mass number and charge on the atom are given. The identity of the element and number of neutron is to be calculated.

Concept introduction: In a neutral atom, the number of protons and electrons are same and equal to the atomic number of that atom but in an ion, they are different in number depending on the charge on the ion. The sum of the number of protons and number of neutrons is equal to the mass number of that atom or ion.

To determine: The identity of the element and number of neutrons.
