Which of the Following Concerning Second Ionization Energies Is True

question 7

Multiple Choice

Which of the following concerning second ionization energies is true?

• A)That of Al is higher than that of Mg because Mg wants to lose the second electron,so it is easier to take the second electron away.
• B)That of Al is higher than that of Mg because the electrons are taken from the same energy level,but the Al atom has one more proton.
• C)That of Al is lower than that of Mg because Mg wants to lose the second electron,thus the energy change is greater.
• D)That of Al is lower than that of Mg because the second electron taken from Al is in a p orbital,thus it is easier to take.
• E)The second ionization energies are equal for Al and Mg.
