The energy required to remove an electron from a gaseous species X to form $$\text{X}^+$$ is known as the first ionization energy (IE) of X, the energy required to remove an electron from $$\text{X}^+$$ to form $$\text{X}^{++}$$ is the second IE of X, and similarly the energy required to remove an electron from $$\text{X}^-$$ to form X is called the IE of $$\text{X}^-$$. Identify the correct statements from the following
