Valence electrons in the element X are 3 and that in element Y is 6. Most probable compound formed from X and Y is
Options
- AX₂ Y
- BX Y₂
- CX₆ Y₃
- DX₂ Y₃
Correct answer
D. X₂ Y₃
Step-by-step solution
Valence electrons in X =3 Valence electrons in Y =6 Thus, X is electropositive and Y is electronegative, X can lose three electrons and Y can gain two electrons to attain stable configuration. Hence, X exists as X ³⁺ and Y as Y ²⁻ and compound is X₂ Y₃ .
