**Instruction:**
In the blank, write the number that completes the chart.

**Chart Explanation:**

- **Element:** Manganese-55
- **# Protons:** 25
- **# Neutrons:** ?
- **# Electrons:** 25

**Description:**
The chart provides information about the atomic structure of Manganese-55, an isotope of manganese. It specifies the number of protons and electrons as 25, leaving the number of neutrons as a question to be filled in. To calculate the number of neutrons, use the formula:

\[ \text{Number of Neutrons} = \text{Mass Number} - \text{Number of Protons} \]

For Manganese-55:
\[ \text{Number of Neutrons} = 55 - 25 = 30 \]

Thus, the completed chart should contain 30 neutrons.
