Question

17) As an electron is brought from an infinite
distance close to the nucleus of the atom, the
energy of the electron - nucleus system:
a) Increase to a greater positive value
b) Decrease to a smaller positive value
c) Decreases to a greater negative value
d) Increases to a smaller negative value​

Answer 1

Answer:

I hope you get your answer and like it....

Explanation:

The energy of an electron is considered as zero at infinite distance from the nucleus as electron come nearer it gets bounded from the nucleus so the energy is negative. Energy is inversely proportional to the distance so, as the distance decreases energy increases to a greater negative value.
