The valence electrons in the element A are 3 and those in element B are 6. The most probable compound formed by A and B is

A

`A_2B`

B

`AB_2`

C

`A_6B_3`

D

`A_2B_3`

Text Solution

Verified by Experts

The correct Answer is:
D
A has three valence electrons, so it forms `A^( +3)` . B has six valence electrons, so it forms B2-. Thus, the compound formed is `A_2B_3` .
