An element 'A' has 3 electron in outermost shell and 'B' has 6 electron in outermost shell. Formula of the compound formed by the combination of these two.
Options:
Answer:
A
Solution:
To form a stable compound, element 'A' (3 valence electrons) will lose 3 electrons, forming A³⁺. Element 'B' (6 valence electrons) will gain 2 electrons, forming B²⁻. To balance charges, two A³⁺ ions combine with three B²⁻ ions, resulting in the formula A₂B₃.
