Rutherford's model didn't not account for the properties of electrons. bohr placed electrons in layers of orbit so C
Oxygen has a strong double bond which has more stability than the single co-ordinate bond in ozone, therefore more energy is required to break the O2 bonding than ozone, so the ozone molecule is more reactive than oxygen gas. ...

Answer: This was because the experiment showed that a substance could emit radiation even while it was not exposed to light.
Answer:
