The electronic configuration of the elements X,Y, Z and J are given below . Which element has the highest metallic character

Options

A. X=2 , 8,4
B. Y = =2 ,8 ,8
C. Z=2,8,8,1
D. J=2,8,8,7

Answer

To determine which element among X, Y, Z, and J has the highest metallic character based on their electronic configurations, we can follow these steps:

### Step 1: Identify the Electronic Configurations
The electronic configurations provided are:
- Element X: 2, 8, 4
- Element Y: 2, 8, 8
- Element Z: 2, 8, 8, 1
- Element J: 2, 8, 8, 7

### Step 2: Determine the Group and Block of Each Element
- **Element X (2, 8, 4)**: The outermost shell has 4 electrons, indicating it belongs to Group 14 (P-block).
- **Element Y (2, 8, 8)**: The outermost shell has 8 electrons, indicating it belongs to Group 18 (P-block, noble gas).
- **Element Z (2, 8, 8, 1)**: The outermost shell has 1 electron, indicating it belongs to Group 1 (S-block).
- **Element J (2, 8, 8, 7)**: The outermost shell has 7 electrons, indicating it belongs to Group 17 (P-block).

### Step 3: Analyze the Metallic Character
- **Metallic Character Trend**: Metallic character increases as you move down a group and decreases as you move from left to right across a period. S-block elements generally exhibit higher metallic character compared to P-block elements.
- **Element Z**: Being in Group 1 (S-block), it has the highest metallic character because it has 1 valence electron, which it can easily lose.
- **Elements X, Y, and J**: These are all P-block elements, and their metallic character is lower than that of S-block elements.

### Step 4: Conclusion
Based on the analysis, Element Z has the highest metallic character due to its position in the periodic table as an S-block element.

### Final Answer
**Element Z has the highest metallic character.**
