Predict the formula of the stable binary compounds that would be formed by the combination of the following pairs of elements



Q.32:- Predict the formula of the stable binary compounds that would be formed by the combination of the following pairs of elements. (a) Lithium and oxygen
(b) Magnesium and nitrogen
(c) Aluminium and iodine
(d) Silicon and oxygen
(e) Phosphorus and fluorine
(f) Element 71 and fluorine

 

 

Answer:-



(a) Li02(Lithium oxide) (b) Mg3N2(Magnesium nitride)
(c) AlI3(Aluminium iodide) (d) Si02 (Silicon dioxide)
(e) Phosphorous and fluorine (f) Z = 71
The element is Lutenium (Lu). Electronic configuration[Xe] 4 f7 5d1 6s2.with fluorine it will form a binary compound = Lu F3.
