Then, calculate the energy required to remove all valence electrons from one gram of magnesium. The first ionization energy is 738.1 kJ/mol, the second ionization energy is 1,450 kJ/mol, and the third ionization energy is 7,730 kJ/mol. Write the equation for the formation of a fluoride anion from a fluorine atom. Fluorine’s electron affinity is +328 kJ/mol. What is ΔH when electrons are added to two moles of fluorine? Writing Section- Please Answer on a Separate Sheet Short Answer (5 points each)- Explain how the modern periodic table came to be. Reference Moseley, Newlands, and Mendeleev in your answer. What is ionization energy? How does ionization energy influence the
