Q. 5.6 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify each of the following:
a. ${}_1{}^1\mathrm{X}$
b. ${}_{35}{}^{81}\mathrm{X}$
c. ${}_0{}^0\mathrm{X}$
d. ${}_{26}{}^{59}\mathrm{X}$
e. ${}_{+1}{}^0\mathrm{X}$

Step-by-Step Solution

Answer

Part(a) It is ${}_1{}^1\mathrm{H}$

Part(b) It is ${}_{35}{}^{81}\mathrm{Br}$

Part(c) It is ${}_0{}^0\mathrm{\gamma }$

Part(d) It is ${}_{26}{}^{59}\mathrm{Fe}$

Part(e) It is ${}_{+1}{}^0\mathrm{e}$

Part(a) Step 1 : Given information

We need to identify ${}_1{}^1\mathrm{X}$

Part(a) Step 2 : Simplify

As we know the symbol ${}_{\mathrm{Z}}{}^{\mathrm{Y}}\mathrm{X}$ represents :

X= atom

Y= mass number

Z= number of proton 

Therefore,

${}_1{}^1\mathrm{X}$ represents ${}_1{}^1\mathrm{H}$ . it is proton having $+1$ charge.

Part(b) Step 1 : Given information

We need to identify ${}_{35}{}^{81}\mathrm{X}$

Part(b) Step 2 : Simplify

As we know the symbol  represents :

X= atom

Y= mass number

Z= number of proton 

Therefore,

From pereodic table we can say ${}_{35}{}^{81}\mathrm{X}$ represents ${}_{35}{}^{81}\mathrm{Br}$

Part(c) Step 1 : Given information

We need to identify ${}_0{}^0\mathrm{X}$

Part(c) Step 2 : Simplify

As we know the symbol  represents :

X= atom

Y= mass number

Z= number of proton 

Therefore,

${}_0{}^0\mathrm{X}$ represents ${}_0{}^0\mathrm{\gamma }$ gamma ray .

Part(d) Step 1 : Given information

We need to identify ${}_{26}{}^{59}\mathrm{X}$

Part(d) Step 2 : Simplify

As we know the symbol  represents :

X= atom

Y= mass number

Z= number of proton 

Therefore, from pereodic table,

${}_{26}{}^{59}\mathrm{X}$ represents ${}_{26}{}^{59}\mathrm{Fe}$

Part(e) Step 1 : Given information

We need to identify ${}_{+1}{}^0\mathrm{X}$

Part(e) Step 2 : Simplify

As we know the symbol  represents :

X= atom

Y= mass number

Z= number of proton 

Therefore,

${}_{+1}{}^0\mathrm{X}$ represents positron ${}_{+1}{}^0\mathrm{e}$
