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 F are 25.0 pm and 72.0 pm , respectively, predict the bond length of the HF molecule.

Answer 1

it's a little hard to see but the bond length would just be the sum of the two radii

Answer 2

97?

Answer 3

97.0 w/ sig figs

Answer 4

so 97.0

Answer 5

units pm?

Answer 6

yes

Answer 7

close but not quite

potential energy reaches a minimum (not zero, but a minimum) at 0.74A so yes, a bond will form at this distance

statement 4 is incorrect (potential energy is only 0 when the atoms are infinitely apart)

so only statements 1,2,3
