Explanation:

Step1: Find the atomic number

The atomic number ($Z$) is equal to the number of protons. Here, the number of protons is 19, so $Z = 19$. The element with atomic number 19 is potassium (K).

Step2: Calculate the mass number

The mass number ($A$) is the sum of protons and neutrons. So $A=19 + 18=37$.

Step3: Construct the isotope symbol

The isotope symbol is written as $^A_Z\text{El}$, where $A$ is the mass number, $Z$ is the atomic number, and $\text{El}$ is the element symbol. Substituting the values, we get $^{37}_{19}\text{K}$.

Answer:

$^{37}_{19}\text{K}$
