WebIonisation energy is the energy needed to remove one mole of electrons from one mole of gaseous atoms under standard conditions. It takes energy to remove electrons because … WebThe energy required to remove the third electron is the third ionization energy, and so on. Energy is always required to remove electrons from atoms or ions, so ionization processes are endothermic and IE values are always positive. For larger atoms, the most loosely bound electron is located farther from the nucleus and so is easier to remove. how long can cream cheese stay unrefrigerated
