What kind of bond is k-o bond in koh?

There is no K-O bond in KOH as this is an ionic compound formed between the cation, K + and the polyatomic anion, OH - So, the electronegative difference here causes this ionic bond to form by attraction in whole as shown above.

Is KF a polar covalent bonds or non-polar covalent or ionic?

KCl is an ionic compound. The electronegativity of potassium (K) is approximately 0.82. The electronegativity of chlorine (Cl) is approximately 3.16. The difference between these electronegativities is 2.34. This high electronegativity difference is what makes potassium chloride an ionic compound. If the electronegativity difference of two elements is greater than 1.7, it is considered to be an ionic compound. If the difference is between 0.4 and 1.7, the compound is considered to be polar covalent. If the difference is less than 0.4, the compound is considered to be covalent. If the difference is 0 (i.e. the two elements are the same), then the compound is considered to be pure covalent. KCl is ionic because K's electronegativity is 0.82 and Cl's is 3.16. A compound is ionic when the electronegativity on the Pauling Scale is more than 2.1. The difference 2.34, so it is ionic.

What is the formula of the ionic compound expected to form between the elements Ba and O?

The ionic compound formed by reaction of the elements with atomic symbols K and O is named potassium oxide and has the formula unit K2O. (The lower case letters k and o are never proper atomic symbols!)

Why is BaO ionic?

BaO is an ionic compound. You can determine it is ionic because the bond exists between a metal (Ba) and a non-metal (O).
