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.

Does SBr2 has polar or nonpolar bonds?
No, it is non-polar.
Is rubidium fluoride a nonpolar covalent polar covalent or ionic bond?
Rubidium by itself is neither ionic nor covalent. When it forms bonds with other elements, it forms ionic bonds.
Is oxygen ionic polar covalent or non polar covalent?
nonpolar covalent
Is pentane nonpolar covalent polar covalent or ionic?
pentane is nonpolar covalent compound
Is dipotassium oxide ionic polar covalent or nonpolar covalent?
Ionic

Is dipotassium oxide ionic polar covalent or nonpolar covalent?
Ionic
Which substance has polar covalent bonds SO2 Cl2 N2 or CaO?
Molecular substances can have both polar and nonpolar covalent bonds.
Is oxygen a polar or a nonpolar bond?
O2 , dioxygen has a non-polar covalent bond. With other elemnts, oxygen can form covalent bonds (generally polar) and ionic bonds as the O2- ion
Is lithium polar covalent?
Lithium is a metal and would form ionic bonds - so extremely polar.
Is NO2- a polar or nonpolar covalent bond or ionic?
NO2^-, the nitrite anion, is made with covalent bonds between N and O. It is polar. When combined with a metal atom, it forms an ionic bond, such as in NaNO2.
Is SI-O bond ionic polar covalent nonpolar covalent?
Polar covalent
What types of elements are involved in a nonpolar bond?
A nonpolar bond could only occur with covalent bonds, as all ionic bonds are polar. This means that all elements involved in nonpolar bonds are nonmetals.
Is SnF4 a polar or nonpolar covalent bond or ionic?
SnF4 wold be a nonpolar molecule, but it has polar covalent bonds. But since there are 4 of them, all equal, they cancel each other and thus the molecule itself is non polar.
