Question

question 2 - 1 point which anion would bond with k+ in a 1 : 1 ratio to form a neutral ionic compound? select the correct answer below: o o2- o f- o n3- o s2-

Explanation:

Step1: Understand ionic - compound charge balance

For a neutral ionic compound, the total positive charge must equal the total negative charge. Potassium ion $K^+$ has a + 1 charge.

Step2: Analyze each anion charge

• $O^{2 - }$ has a - 2 charge. A 1:1 ratio with $K^+$ would result in a net - 1 charge ($+1+( - 2)=-1$).
• $F^-$ has a - 1 charge. A 1:1 ratio with $K^+$ gives a net 0 charge ($+1+( - 1)=0$).
• $N^{3 - }$ has a - 3 charge. A 1:1 ratio with $K^+$ would result in a net - 2 charge ($+1+( - 3)=-2$).
• $S^{2 - }$ has a - 2 charge. A 1:1 ratio with $K^+$ would result in a net - 1 charge ($+1+( - 2)=-1$). So the anion that bonds with $K^+$ in a 1:1 ratio to form a neutral ionic compound is $F^-$.

Answer:

B. $F^-$
