91. Which of the following atoms would have the largest second ionization energy?
ANSWER: e
POINTS: 1
92. The first ionization energy of Mg is 735 kJ/mol. The second ionization energy is: a. 735 kJ/mol. b. less than 735 kJ/mol. c. greater than 735 kJ/mol. d. more information is needed to answer this question. e. none of these.
ANSWER: c
POINTS: 1 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.
93. Which of the following concerning second ionization energies is true?
ANSWER: b
POINTS: 1 a. 1 : 4 b. 4 : 1
94. Consider a planet where the temperature is so high that the ground state of an electron in the hydrogen atom is n = 4. What is the ratio of ionization energy for hydrogen on this planet compared to that on Earth?
