Answer: Electrons positioned closer to the nucleus have a greater attraction to the protons and are more likely to be discharged from the atom than electrons farther away.
Explanation: The electrons being negatively charged repel each other due to like charges. The protons being positively charged are attracted towards the negatively charged electrons.
The electrons which are near to nucleus are more tightly held by the protons and thus are more difficult to remove from the atom. The electrons which are far from the nucleus are less tightly held and are easily removed from the atom.
