Chapter 4.3, Problem 19SP

(a)

Interpretation Introduction

Interpretation : The composition of each atom in shorthand form is to be expressed.

Concept Introduction : The atomic number and mass number can be used to express the make-up of any atom in shorthand form.

Answer to Problem 19SP

The composition of carbon-12 in shorthand form is ${}_{\text{6}}^{\text{12}}\text{C}$ .

Explanation of Solution

The atomic number and mass number can be used to express the make-up of any atom in abbreviated form. Each element has a unique chemical symbol.

The atomic number appears as the subscript in shorthand notation, and the mass number appears as the superscript.

In the given atom carbon-12, 12 represents the mass number while the carbon’s atomic number is 6. The symbol of carbon is $\text{C}$ .

So, the atom in shorthand form is written as ${}_{\text{6}}^{\text{12}}\text{C}$ .

(b)

Interpretation Introduction

Concept Introduction : The atomic number and mass number can be used to express the make-up of any atom in shorthand form.

Answer to Problem 19SP

The composition of boron-11 in shorthand form is ${}_{\text{5}}^{\text{11}}\text{B}$ .

Explanation of Solution

The atomic number and mass number can be used to express the make-up of any atom in abbreviated form. Each element has a unique chemical symbol.

The atomic number appears as the subscript in shorthand notation, and the mass number appears as the superscript.

In the given atom boron-11, 11 represents the mass number while the boron’s atomic number is 11. The symbol of boron is $\text{B}$ .

So, the atom in shorthand form is written as ${}_{\text{5}}^{\text{11}}\text{B}$ .

(c)

Interpretation Introduction

Interpretation : The composition of each atom in shorthand form is to be expressed.

Concept Introduction : The atomic number and mass number can be used to express the make-up of any atom in shorthand form.

Answer to Problem 19SP

The composition of beryllium-9 in shorthand form is ${}_{\text{4}}^{\text{9}}\text{Be}$ .

Explanation of Solution

The atomic number and mass number can be used to express the make-up of any atom in abbreviated form. Each element has a unique chemical symbol.

The atomic number appears as the subscript in shorthand notation, and the mass number appears as the superscript.

In the given atom beryllium-9, 9 represents the mass number while the beryllium’s atomic number is 4. The symbol of beryllium is $\text{Be}$ .

So, the atom in shorthand form is written as ${}_{\text{4}}^{\text{9}}\text{Be}$ .

(d)

Interpretation Introduction

Interpretation : The composition of each atom in shorthand form is to be expressed.

Concept Introduction : The atomic number and mass number can be used to express the make-up of any atom in shorthand form.

Answer to Problem 19SP

The composition of oxygen-16 in shorthand form is ${}_8^{\text{16}}\text{O}$ .

Explanation of Solution

The atomic number and mass number can be used to express the make-up of any atom in abbreviated form. Each element has a unique chemical symbol.

The atomic number appears as the subscript in shorthand notation, and the mass number appears as the superscript.

In the given atom oxygen-16, 16 represents the mass number while the oxygen’s atomic number is 8. The symbol of oxygen is $\text{O}$ .

So, the atom in shorthand form is written as ${}_8^{\text{16}}\text{O}$ .
