C. N3-

D. S2-

B. F⁻

Explanation:

Which anion would bond with K⁺ in a 1:1 ratio to form a neutral ionic compound?

Select the correct answer below:

A. O²⁻. NO. K⁺ and O²⁻ form K₂O in a 2:1 molar ratio.

B. F⁻. YES. K⁺ and F⁻ form KF in a 1:1 molar ratio.

C. N³⁻. NO. K⁺ and N³⁻ form K₃N in a 3:1 molar ratio.

D. S²⁻. NO. K⁺ and S²⁻ form K₂S in a 2:1 molar ratio.
