Question

An atom a has 3 electrons in its valence shell and atom b has 6 electrons in its valence shell then find the compound

Answer 1

Answer:

A2B3. Plzz mark as brainliest

Explanation:

As a atom has 3 electrons in valance shell it will have a charge of +5 or -3

And as atom b has 6 electrons in valence shell it will have a charge of +6 or -2

For a it is easier to five 3 electeons than to take 5. Hence, elemnet is A3

For b it is easier to take 2 electrons than to give 6. Therefore, element is B with a charge -2

Now,

A×3=B× -2

Cross multiplying for compound formation:-

The comppund is A2B3.
