An atom of element A has 3 electrons in ...

An atom of element A has 3 electrons in its valence shell and an atom of B has 6 electrons in its valence shell. The formula of the compound between these two atoms will be :

A

`A_(3)B_(6)`

B

`A_(2)B_(3)`

C

`A_(3) B_(2)`

D

`A_(2)B`

Text Solution
