Chapter 20, Problem 5STP

To determine

The number of neutrons in $Carbon-13$ .

Answer to Problem 5STP

The number of neutrons in $Carbon-13$ is $7$ .

Explanation of Solution

Given information:

Atomic number of Carbon is 6.

Mass number is 13

Formula used:

Write the expression for the number of neutrons for an atom.

  $\mathrm{The}numberofneutrons=Massnumber–Atomicnumber.$

Calculation:

Substitute the values in the above expressions:

  $\begin{array}{c}\mathrm{The}numberofneutrons=Massnumber–Atomicnumber.\\ =13-6\\ =7\end{array}$

Thus, the number of neutrons in $Carbon-13$ is 7.

Conclusion:

Thus, the number of neutronsin $Carbon-13$ is 7.
