Most abundand and most reactive element of group VIA elements

Options

A. O, O
B. O, S
C. O, Po
D. S, O

Answer

To determine the most abundant and most reactive element of the group VIA (or Group 16) elements, let's analyze the elements in this group step by step.

### Step-by-Step Solution:

1. **Identify the Group VIA Elements**:
- The elements in Group VIA (or Group 16) are: Oxygen (O), Sulfur (S), Selenium (Se), Tellurium (Te), and Polonium (Po).

2. **Determine the Most Abundant Element**:
- To find the most abundant element, we can refer to the abundance of elements in the Earth's crust and atmosphere.
- Among the Group VIA elements, oxygen is the most abundant element on Earth. It is a major component of the atmosphere and is present in water and many minerals.

3. **Determine the Most Reactive Element**:
- Reactivity in nonmetals, particularly in Group VIA, is often related to electronegativity. The more electronegative an element, the more reactive it tends to be.
- Oxygen is the second most electronegative element in the periodic table (after fluorine), which indicates a high tendency to react with other elements. This makes oxygen the most reactive element in Group VIA.

4. **Conclusion**:
- Therefore, both the most abundant and the most reactive element in Group VIA is **Oxygen (O)**.

### Final Answer:
- The most abundant and most reactive element of Group VIA elements is **Oxygen (O)**.
