Y 7 4 3 2 1 Binding Energy (MJ/mol) The complete photoelectron spectrum of an element is given above. Which labeled peak corresponds to the 1s electrons and why? Peak X, because 1s electrons are the easiest to remove from the atom. B) Peak X, because 1s electrons have the strongest attractions to the nucleus. Peak Y, because electrons in the 1s sublevel are the farthest from the nucleus. Peak Y, because there are fewer electrons in an s sublevel than in a p sublevel. Relative Numbe of Electrons
