Question

Quizplus · Accepted Answer

The pattern of the first six ionization energies for Si is: I₁: 786.5 kJ/mol I₂: 1577.1 kJ/mol I₃: 3231.6 kJ/mol I₄: 4355.5 kJ/mol I₅: 16091 kJ/mol I₆: 19805 kJ/mol This pattern shows a gradual increase in ionization energy with each successive removal of an electron, with a significant jump in energy between the fourth and fifth ionization energies, indicating the removal of a core electron. None of the other elements listed have a similar pattern in their ionization energies.
