The worth of subscript to finish the offered formula will 1 and 1 for both the elements

Explanation:

In the provided formula Al is the price of aluminium metal and N is symbol of nitrogen atom.

You are watching: What subscripts would properly complete the formula unit al_n_?

Aluminium has tendency to looses three electrons from its valence covering to acquire noble gas configuration whereby as nitrogen atom has propensity to obtain three electron to achieve noble gas configuration. Through loosing 3 electrons aluminium atom will get converted right into aluminium cation v 3+ fee (

)and by acquiring three electrons nitrogen atom will acquire converted into nitride ion (
). So, if the move of three electrons native aluminum atom come nitrogen atom occurs, the compound us will acquire will be AlN that is aluminum nitride.

Hence, the value of subscript to complete the offered formula will :x=1, y=1

Answer is C. Potassium ion has actually +1, oxygen -2.2K(+1) + O(-2) = K2O

I believe that it would be Al1N1.

The subscripts that would certainly properly finish the formula unit would certainly be 1 for both. This link is referred to as aluminum nitride. The is a ceramic form of material that which has outstanding properties. Hope this answers the question. Have a blessed day.
