I read something about ionization energy that confused me. Could someone explain what this bold part in the text below is saying? Is it saying that another atom of the same substance attracted to its own ions? Wouldn’t it just be that the loss of an electron allows the positive nucleus to pull in the valence electrons and therefore it is more difficult to displace an electron? Thank you in advance!
“When considering an initially neutral atom, expelling the first electron will require less energy than expelling the second, the second will require less energy than the third, and so on. Each successive electron requires more energy to be released. This is because after the first electron is lost, the overall charge of the atom becomes positive, and the negative forces of the electron will be attracted to the positive charge of the newly formed ion. The more electrons that are lost, the more positive this ion will be, the harder it is to separate the electrons from the atom.”
