Chapter 4, Problem 75A

Interpretation Introduction

(a)

Interpretation:

Protons and electrons in the atom of V is to be calculated.

Concept introduction:

Atomic number of an atom is alsoreferred as number of protons present in an atom. All atoms are neutral.

Answer to Problem 75A

V

Element name − Vanadium

$\begin{array}{l}\text{Number of protons = 23}\hfill \\ \text{Number of electrons = 23}\hfill \end{array}$

Explanation of Solution

V

Elements name is Vanadium.

Atomic number of Vanadium is 23.

$\begin{array}{l}\text{Atomic number = number of protons}\hfill \\ \text{Number of protons = 23}\hfill \end{array}$

As, all atoms are neutral

$\begin{array}{l}\text{Number of electrons = Number of protons}\hfill \\ \text{Number of electrons = 23}\hfill \end{array}$

Interpretation Introduction

(b)

Interpretation:

Protons and electrons in the atom of Mn is to be calculated.

Concept introduction:

Atomic number of an atom is alsoreferred as Number of protons present in an atom. All atoms are neutral.

Answer to Problem 75A

Mn

Element name − Manganese

$\begin{array}{l}\text{Number of protons = 25}\hfill \\ \text{Number of electrons = 25}\hfill \end{array}$

Explanation of Solution

Mn

Elements name is Manganese.

Atomic number of Manganese is 25.

$\begin{array}{l}\text{Atomic number = number of protons}\hfill \\ \text{Number of protons = 25}\hfill \end{array}$

As, all atoms are neutral

$\begin{array}{l}\text{Number of electrons = Number of protons}\hfill \\ \text{Number of electrons = 25}\hfill \end{array}$

Interpretation Introduction

(c)

Interpretation:

Protons and electrons in the atom of Ir is to be calculated.

Concept introduction:

Atomic number of an atom is alsoreferred as Number of protons present in an atom. All atoms are neutral.

Answer to Problem 75A

Ir

Element name − Iridium

$\begin{array}{l}\text{Number of protons = 77}\hfill \\ \text{Number of electrons = 77}\hfill \end{array}$

Explanation of Solution

Ir

Elements name is Iridium.

Atomic number of Iridium is 77.

$\begin{array}{l}\text{Atomic number = number of protons}\hfill \\ \text{Number of protons = 77}\hfill \end{array}$

As, all atoms are neutral

$\begin{array}{l}\text{Number of electrons = Number of protons}\hfill \\ \text{Number of electrons = 77}\hfill \end{array}$

Interpretation Introduction

(d)

Interpretation:

Protons and electrons in the atom of S is to be calculated.

Concept introduction:

Atomic number of an atom is alsoreferred as Number of protons present in an atom. All atoms are neutral.

Answer to Problem 75A

S

Element name − Sulfur

$\begin{array}{l}\text{Number of protons = 16}\hfill \\ \text{Number of electrons = 16}\hfill \end{array}$

Explanation of Solution

S

Elements name is Sulfur

Atomic number of Sulfur is 16

$\begin{array}{l}\text{Atomic number = number of protons}\hfill \\ \text{Number of protons = 16}\hfill \end{array}$

As, all atoms are neutral

$\begin{array}{l}\text{Number of electrons = Number of protons}\hfill \\ \text{Number of electrons = 16}\hfill \end{array}$
