Question
The image contains two mass spectrometry graphs, each illustrating the relative abundance of various isotopes of an element.

### Graph Analysis:

#### Left Graph:
- **Axes:** 
  - Y-axis: Relative Abundance, ranging from 0 to 100.
  - X-axis: Mass-to-charge ratio (m/z), with values ranging from 0 to 12.
- **Details:** 
  - This graph shows several peaks, with a prominent peak around m/z = 12, indicating the most abundant isotope.

#### Right Graph:
- **Axes:**
  - Y-axis: Relative Abundance (%), ranging from 0 to 100.
  - X-axis: Mass-to-charge ratio (m/z), with values from 88 to 98.
- **Details:** 
  - This graph displays multiple peaks, with a notable peak at m/z = 90, suggesting the most prevalent isotope.

### Educational Task:
For each of the two Mass Spec Graphs:

1. Determine the average atomic mass.
2. Identify the element.
3. Write the symbol for each isotope.
4. Indicate the number of protons, electrons, and neutrons for each isotope.

This exercise helps students understand how to interpret mass spectrometry data to identify elements and their isotopic composition.
