![The image shows the notation for an isotope with the following symbols:
- \( \frac{A}{Z} \text{X} \)
Below this, the text reads:
"What is the calcium isotope with 20 neutrons?"
### Explanation:
- **A** represents the mass number (sum of protons and neutrons).
- **Z** represents the atomic number (number of protons).
- **X** is the chemical symbol of the element.
To find the calcium isotope with 20 neutrons:
Calcium has an atomic number (Z) of 20. Therefore, the equation for the mass number (A) is:
\[ A = \text{protons} + \text{neutrons} = 20 + 20 = 40 \]
Thus, the calcium isotope is \( \text{Ca-40} \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4621e266-56d0-4bb0-84d9-29c60fad2380%2F0c961e7c-9def-4646-b1b3-fc66667a5ab2%2F3uzohb_processed.jpeg&w=3840&q=75)
