An atom of an element A has three electron in its outer shell and `B`

1.	An atom of an element A has three electron in its outer shell and `B` has six electron in outermost shell. The formula of the compound formed between these two will beA. `A_(6)B_(6)`B. `A_(2)B_(3)`C. `A_(3)B_(2)`D. `A_(2)B`
Answer» Correct Answer - b In this case the valence electron in the atom `A` is three and hence its generally `3`. In the atom `B` the number of valence electron is six. Hence its valency is usually `2` Hence the formula of the molecule formed from `A and B` could br `A_(2)B_(2)`. An example of two such elements are `AI` and `O` and the formula of Aluminium oxide is `AI_(2)O_(3)`.
