The second ionization energy value of magnesium ion after the removal of the second electron is?
Correct answer: D. 773 KJ/mol
- A. 135 KJ/mol
- B. 145 KJ/mol
- C. 155 KJ/mol
- D. 773 KJ/mol
Explanation
Elements with a greater number of electrons have more than one value of ionization energy. So, for magnesium, the first ionization energy value is the energy required to remove the first electron. IE1 = 738 kJ/molSimilarly, the second ionization energy value is the energy required to remove the second electron from a positively charged ion.nIE2 = 1145kJ/molPTB XII Chap # 1 page # 6 & 7

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
