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 will follow these steps:

### Step 1: Identify the Electronic Configurations
Let's first identify the electronic configurations of the elements:
- Element X: 2, 8, 4
- Element Y: 2, 8, 1, 8
- Element Z: 2, 8, 18
- Element J: 2, 8, 7, 35

### Step 2: Determine the Group and Period of Each Element
Next, we need to determine the group and period for each element based on their electronic configurations:
- Element X (2, 8, 4): This configuration suggests it is in Group 14 (Carbon group).
- Element Y (2, 8, 1, 8): This configuration suggests it is in Group 1 (Alkali metals).
- Element Z (2, 8, 18): This configuration suggests it is in Group 18 (Noble gases).
- Element J (2, 8, 7, 35): This configuration suggests it is in Group 17 (Halogens).

### Step 3: Analyze Metallic Character
Now, we analyze the metallic character based on the groups:
- **Alkali Metals (Group 1)**: Elements in this group have the highest metallic character because they can easily lose one electron.
- **Group 14 (Carbon Group)**: These elements have a moderate metallic character, as they can lose or gain electrons.
- **Group 17 (Halogens)**: These elements are non-metals and have low metallic character.
- **Noble Gases (Group 18)**: These elements are inert and do not exhibit metallic character.

### Step 4: Compare the Elements
Based on the analysis:
- Element Y (Group 1) has the highest metallic character as it is an alkali metal.
- Element X (Group 14) has moderate metallic character.
- Element J (Group 17) has low metallic character.
- Element Z (Group 18) has no metallic character.

### Conclusion
Therefore, the element with the highest metallic character is **Element Y**.
