Bond length is the distance between the centers of two bonded atoms. On the potential energy curve, the bond length is the internuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Given that the atomic radii of H and Br are 25.0 pm and 115 pm , respectively, predict the bond length of the HBr molecule. Express your answer to three significant figures and include the appropriate units. in nm please
