Chapter 3, Problem 3.13PP

a.

Summary Introduction

To determine:

The number of protons and electron present in ${\text{Ca}}^{2+}$ ion.

Introduction:

The electrons, protons, and neutrons are sub atomic particles. The number of protons and electrons present in an element are equal which forms the atomic number of the element $\left(Z\right)$. The relation between atomic number, atomic mass $\left(A\right)$ , and number of neutrons $\left(N\right)$ is stated by the formula,

$A=N+Z$

b.

Summary Introduction

To determine:

The number of protons and electron present in ${\text{I}}^{-}$ ion.

Introduction:

The electrons, protons, and neutrons are sub atomic particles. The number of protons and electrons present in an element are equal which forms the atomic number of the element $\left(Z\right)$. The relation between atomic number, atomic mass $\left(A\right)$ , and number of neutrons $\left(N\right)$ is stated by the formula,

$A=N+Z$

c.

Summary Introduction

To determine:

The number of protons and electron present in ${\text{S}}^{2-}$ ion.

Introduction:

The electrons, protons, and neutrons are sub atomic particles. The number of protons and electrons present in an element are equal which forms the atomic number of the element $\left(Z\right)$. The relation between atomic number, atomic mass $\left(A\right)$ , and number of neutrons $\left(N\right)$ is stated by the formula,

$A=N+Z$

d.

Summary Introduction
