To find the number of neutrons in an isotope, you can use the following formula:
\[
\text{Number of neutrons} = \text{Mass number} - \text{Atomic number}
\]
For the isotope \({}^{23}_{11}\text{Na}\):
- The mass number (the upper number) is \(23\).
- The atomic number (the lower number) is \(11\).
Now, substitute these values into the formula:
\[
\text{Number of neutrons} = 23 - 11 = 12
\]
Thus, \({}^{23}_{11}\text{Na}\) has **12 neutrons**.
