Q.5.2 - An Introduction to General, Organic, and Biological Chemistry

Question

Identify the type of particle or radiation for each of the following:

a. ${}_{-1}{}^0\mathrm{e}$

b. ${}_1{}^1\mathrm{H}$

c. ${}_0{}^1\mathrm{n}$

Step-by-Step Solution

Answer

a. It is a beta particle.

b. It is a proton.

c. It is a neutron.

Step 1: Part (a) Given Information

We need to identify this particle: ${}_{-1}{}^0\mathrm{e}$

Step 2: Part (a) Explanation

A beta particle is a  high-energy electron and it has a charge of $1-$, and because its mass is very less than the mass of a proton, it has a mass number of zero. It is represented by the $\left(\mathrm{\beta }\right)$.

Thus, ${}_{-1}{}^0\mathrm{e}$ is a beta particle.

Step 1: Part (b) Given Information

We need to identify this particle:  ${}_1{}^1\mathrm{H}$

Step 2: Part (b) Explanation

This particle is known as proton which is represented as ${}_1{}^1\mathrm{H}$. The mass number for proton is 1 and it has a charge of $\left(1+\right)$.

Step 1: Part (c) Given Information

We need to identify this particle: ${}_0{}^1\mathrm{n}$

Step 2: Part (c) Explanation

This particle is known as a neutron. It is represented as ${}_0{}^1\mathrm{n}$. The mass number for neutron is 1 and it has a zero charge.
