The second most electronegative element in periodic table is

Options

A. F
B. O
C. Cl
D. N

Answer

To determine the second most electronegative element in the periodic table, we can follow these steps:

### Step 1: Understand Electronegativity
Electronegativity is the tendency of an atom to attract electrons in a chemical bond. The higher the electronegativity, the more an atom attracts electrons.

### Step 2: Identify the Most Electronegative Element
In the periodic table, fluorine (F) is known to be the most electronegative element with an electronegativity value of 4.0 on the Pauling scale.

### Step 3: Compare Other Elements
We need to compare the electronegativity values of the other elements in the options provided: oxygen (O), chlorine (Cl), and nitrogen (N).

- **Oxygen (O)**: Electronegativity value of about 3.5
- **Chlorine (Cl)**: Electronegativity value of about 3.0
- **Nitrogen (N)**: Electronegativity value of about 3.0

### Step 4: Determine the Second Most Electronegative Element
From the comparison:
- Fluorine (F) is the most electronegative.
- Oxygen (O) is the second most electronegative.

### Conclusion
Thus, the second most electronegative element in the periodic table is **oxygen (O)**.
