An atom of an element A has three electrons in its outermost orbit and...
A has 3 electrons in outermost orbit and B has 6 electrons in its outermost orbits. So A can give three electrons to complete its octet and B needs 2 electrons to complete its octet. So 2 atoms of A will release 6 electrons and 3 atoms of B will need six electrons to complete their octet
So, the formula will be A2B3
So, the formula will be A2B3

Explanation:
When two elements combine to form a compound, they do so in a way that the resulting compound is stable. Elements achieve stability by either gaining, losing, or sharing electrons to attain a complete outermost electron shell.
In this case, element A has three electrons in its outermost orbit, while element B has six electrons in its outermost orbit. Both elements need to either lose or gain electrons to achieve stability.
Formation of Compound:
To achieve stability, element A can lose its three outermost electrons, resulting in a positive charge of +3. On the other hand, element B can gain two electrons to complete its outermost shell, resulting in a negative charge of -2.
When element A and element B combine, their charges must be balanced. The compound formed will have the formula A2B3, where A2 indicates that two atoms of element A are present, and B3 indicates that three atoms of element B are present.
Explanation of Options:
Option A: A0B6 - This option suggests that element A has zero electrons, which is not possible. Elements cannot exist without any electrons.
Option B: A2B3 - This is the correct answer, as explained above.
Option C: A3B2 - This option suggests that element A has three atoms, which is not mentioned in the question. The question only provides information about the number of electrons in the outermost orbit.
Option D: A2B - This option suggests that only one atom of element B is present, which does not account for the six electrons in its outermost orbit.
Therefore, the correct formula of the compound formed between element A and element B is A2B3.
