Answer:
Thomson's atomic model was successful in explaining the overall neutrality of the atom. However, its propositions were not consistent with the results of later experiments. In 1906, J. J. Thomson was awarded the Nobel Prize in physics for his theories and experiments on electricity conduction by gases.
Summary. J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."

Explanation:
Halogen group:This group contains Cl,F,Br and I
There are 7 electrons in the outermost shell of each element of halogen family.
Each element of this family required one electron to fill their complete outermost shell.
We know that
Cl=17=
Therefore, the general configuration for atoms of the halogen group is given by
