Answer #1

According to Coulomb's law, same charges repel each other and opposite charges attract each other. The force of attraction is directly proportional to the product of the charges and inversely proportional to the square of distance between them .

Force of attraction ; F q 1 * q 2/r 2

q 1 = total charge of protons

q 2 = total charge of elelectrons

r = distance between two charges.

Therefore force of attraction more for the neutral species.

Now, when the first proton is removed the positive charge is decreased than neutral species. Consequently force of attraction is also decreased.

Hence, to remove the second proton requires less energy compared to first .
