Valence electrons in the atom of element A is 4 and in the element B is 2. Most probable compound formed from A and B is

Options

A. `A_(2)B_(3)`
B. `AB_(2)`
C. `AB_(2)`
D. `A_(2)B`

Answer

To determine the most probable compound formed from elements A and B based on their valence electrons, we can follow these steps:

### Step 1: Identify the Valence Electrons
- Element A has 4 valence electrons.
- Element B has 2 valence electrons.

### Step 2: Write Down the Elements
- Let’s denote element A as A and element B as B.

### Step 3: Cross Multiply the Valence Electrons
- To find the ratio of elements in the compound, we cross multiply the valence electrons:
- For A: 2 (valence electrons of B)
- For B: 4 (valence electrons of A)

This gives us:
- A: 2
- B: 4

### Step 4: Simplify the Ratio
- The ratio we have is 4:2.
- To simplify it, we divide both numbers by their greatest common factor, which is 2:
- 4 ÷ 2 = 2
- 2 ÷ 2 = 1

This gives us a simplified ratio of 2:1.

### Step 5: Write the Compound Formula
- From the simplified ratio, we can write the formula for the compound as:
- A₂B

### Conclusion
The most probable compound formed from elements A and B is A₂B.
