If the electronic distribution of X is 2, 8, 3 and Y is 2, 6, then, the formula of the compound formed is

Options

A. XY
B. `X_2Y_3`
C. `X`
D. `XY_3`

Explanation

To determine the formula of the compound formed by elements X and Y based on their electronic distributions, we can follow these steps:

### Step 1: Identify the electronic configurations
- Element X has an electronic distribution of 2, 8, 3. This means it has 3 valence electrons (the electrons in the outermost shell).
- Element Y has an electronic distribution of 2, 6. This means it has 6 valence electrons.

### Step 2: Determine the valence of each element
- For element X (with 3 valence electrons), it tends to lose these electrons to achieve a stable noble gas configuration. Therefore, the valence of X is +3.
- For element Y (with 6 valence electrons), it tends to gain 2 electrons to achieve a stable noble gas configuration. Therefore, the valence of Y is -2.

### Step 3: Write the formula based on the valences
- The formula of the compound can be derived from the valences of the two elements. To balance the charges, we need to ensure that the total positive charge equals the total negative charge.
- Since X has a valence of +3 and Y has a valence of -2, we can find the lowest common multiple of the valences to determine the ratio in which they combine. The lowest common multiple of 3 and 2 is 6.
- To achieve this, we need 2 X atoms (2 * +3 = +6) and 3 Y atoms (3 * -2 = -6).

### Step 4: Combine the ratios to form the compound
- Therefore, the formula of the compound formed will be X₂Y₃.

### Final Answer
The formula of the compound formed is X₂Y₃.
