Chapter 2, Problem 72AE

Interpretation Introduction

Interpretation: The identity and charge of ion having $2.55\times {10}^{-26}\text{g}$ electrons and $5.34\times {10}^{-23}\text{g}$ protons are to be stated. The symbol and the mass number of neutral atom having $3.92\times {10}^{-26}\text{g}$ electrons and $9.35\times {10}^{-23}\text{g}$ of neutrons are to be stated.

Concept introduction: Three fundamental particles constituting atoms are electrons, protons as well as neutrons.The knowledge of these particles and their respective mass is useful in predicting the element’s atomic number as well as its respective mass number. The respective numbers corresponding to protons along with electrons can be used for evaluating element’s charge.
