Which of the following elements represents highly electropositive as well as highly electronegativity element in its period. ?

Options

A. nitrogen
B. fluorine
C. hydrogen
D. none

Explanation

To solve the question of which element represents both highly electropositive and highly electronegative characteristics in its period, we can follow these steps:

### Step 1: Understand the Terms
- **Electropositive**: An element that readily loses electrons to form positive ions (cations).
- **Electronegative**: An element that readily gains electrons to form negative ions (anions).

### Step 2: Analyze the Options
The options provided are:
1. Nitrogen
2. Chlorine
3. Hydrogen
4. None of these

### Step 3: Examine Each Element
- **Nitrogen (N)**:
- Atomic number: 7
- Configuration: 1s² 2s² 2p³
- Nitrogen can gain three electrons to achieve a stable octet but does not readily lose electrons, so it is not highly electropositive.

- **Chlorine (Cl)**:
- Atomic number: 17
- Configuration: 1s² 2s² 2p⁶ 3s² 3p⁵
- Chlorine is highly electronegative and readily gains one electron to complete its octet, but it does not exhibit electropositive behavior.

- **Hydrogen (H)**:
- Atomic number: 1
- Configuration: 1s¹
- Hydrogen can lose one electron to form H⁺ (making it electropositive) or gain one electron to form H⁻ (making it electronegative). Thus, it can exhibit both behaviors.

- **None of these**: This option implies that none of the above elements fit the criteria, which we will evaluate after analyzing the others.

### Step 4: Conclusion
Based on the analysis:
- Hydrogen is the only element that can act as both electropositive and electronegative in its period (the first period). Therefore, the correct answer is **Hydrogen**.

### Final Answer
The element that represents both highly electropositive and highly electronegative characteristics in its period is **Hydrogen**.
