[单选题]
The successive ionization energies in $kJ mol^{-1}$ for an element in the second period of the periodic table are 800, 2430, 3660, and 25000. Which element is this most likely to be?
A. Element Li
B. Element Be
C. Element B
D. Element C
参考答案: C
本题详细解析:
There is a large increase between the 3rd and 4th ionization energies which shows that the element is in group 13.
Large increases in ionization energy indicate electrons being removed from a shell closer to the nucleus.
