Pearson Chemistry textbook cover with colorful element visuals and atomic data.

It looks like you've uploaded an image of the cover of a chemistry textbook titled "Pearson Chemistry", featuring elements from the periodic table with their atomic numbers, symbols, names, and atomic masses. The elements shown are:

- Carbon (C) – 6, 12.011
- Nitrogen (N) – 7, 14.007
- Oxygen (O) – 8, 15.999
- Silicon (Si) – 14, 28.086
- Phosphorus (P) – 15, 30.974
- Sulfur (S) – 16, 32.06
- Germanium (Ge) – 32, 72.63
- Arsenic (As) – 33, 74.922
- Selenium (Se) – 34, 78.96

However, you mentioned a "task" in the image, but no specific question or problem is visible in the cover image itself. It appears to be just the book cover.

Possible Interpretations:

If this was meant to represent a task, here are some common types of problems that might be associated with such an image:

1. Identify Trends in the Periodic Table
For example:
- Which element has the highest atomic mass? → Selenium (Se) at 78.96
- Which element is a metalloid? → Silicon (Si), Germanium (Ge), Arsenic (As), Selenium (Se)
- What trend do you observe in atomic mass as you move across a period? → Atomic mass increases left to right.

2. Predict Chemical Properties
Based on group and period:
- Oxygen is highly electronegative; it tends to form oxides.
- Phosphorus forms phosphates in biological systems.
- Arsenic is toxic and used in pesticides.

3. Classification Task
- Classify each element as metal, nonmetal, or metalloid:
- C, N, O, P, S → Nonmetals
- Si, Ge → Metalloids
- As → Metalloid (borderline)
- Se → Nonmetal

4. Write Electron Configurations
Example: Oxygen (O, Z=8): 1s² 2s² 2p⁴

If You Have a Specific Task:

Please clarify what the actual problem or question is. For example:
- Are you supposed to find the average atomic mass?
- Identify which elements are in the same group?
- Determine which one is most reactive?
