Question

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 37.0 pm and 115 pm , respectively, predict the upper limit of the bond length of the HBr molecule. Express your answer to three significant figures and include the appropriate units. View Available Hint(s)for Part C

Answer 1

The answer is "152 pm".

Step-by-step explanation:

The bond length from the values inside the atomic radii is calculated according to the query. This would be the upper limit of a molecule's binding length.

The atomic radius of
`H= 37.0 \ pm`

The atomic radius of
`Br = 115.0 \ pm`

`\text{Bond length = Atomic radius of H + Atomic radius of Br}`

`= 37.0\ pm + 115.0 \ pm\\\\= 152\ pm`
