Chapter 10.1, Problem 10.2P

Interpretation Introduction

(a)

Interpretation:

The atomic number should be determined for the nucleus which is shown in following diagram.

  

Concept Introduction:

The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.

Interpretation Introduction

(b)

Interpretation:

The mass number should be determined for the nucleus which is shown in following diagram.

  

Concept Introduction:

The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.

Interpretation Introduction

(c)

Interpretation:

The number of protons should be determined for the nucleus which is shown in following diagram.

  

Concept Introduction:

The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.

Interpretation Introduction

(d)

Interpretation:

The number of neutrons should be determined for the nucleus which is shown in following diagram.

  

Concept Introduction:

The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.

Interpretation Introduction

(e)

Interpretation:

The isotope symbol should be determined for the nucleus which is shown in following diagram.

  

Concept Introduction:

The atomic number is equal to the number of protons of an element whereas sum of number of protons and number of neutrons is equal to mass number.

A form of chemical element having same atomic number but differ by mass number is known as isotopes. In nuclide notation of isotope, the mass number of the isotope is present in superscript in front of the symbol of given element and atomic number is present in subscript in front of the symbol of the element.

The expression is given by: $\text{X}$

where, A = mass number and Z = atomic number
