which type of bond will most likely be found in hbr given that the electronegativity of hydrogen is 2.20 and the electronegativity of bromine is 2.96?
an ionic bond
a metallic bond
a polar covalent bond
a nonpolar covalent bond

Explanation:

1. Calculate electronegativity difference: $2.96 - 2.20 = 0.76$
2. Ionic bonds require differences > 1.7, nonpolar covalent < 0.4, and polar covalent falls between 0.4-1.7. This difference fits polar covalent. Metallic bonds occur between metals, which H and Br are not.

Answer:

a polar covalent bond
