The electron dot diagram you described has 2 dots above and to the right, and 1 dot each below and to the left. This arrangement can be interpreted as the valence electrons of an atom.
Let's analyze the valence electrons for the elements you've listed:
- **Carbon (C)** has 4 valence electrons. Its electron dot structure would show one dot in each of the four directions (4 total).
- **Tellurium (Te)** has 6 valence electrons, which means it would have 6 dots typically arranged around the symbol.
- **Beryllium (Be)** has 2 valence electrons; it would show 2 dots, likely both above or next to each other.
- **Cesium (Cs)** has 1 valence electron, which would show as a single dot.
Given your description of the arrangement of dots, it doesn't match any of these elements precisely. However, the arrangement you provided (2 dots above and right, 1 dot below and left) aligns with the electron configuration of **Selenium (Se)**, which has 6 valence electrons as a non-listed option.
Among the listed choices, none fit exactly, but if we consider only the valence count, **Tellurium (Te)** is the closest, as it has 6 valence electrons, but the specific arrangement doesn't align perfectly.
The best answer from the choices provided is **Tellurium (Te)**, as it is the only element listed that fits the valence electron count.
