在英文维基百科111号元素錀词条下有这样一段描述：
Gold also forms a somewhat stable −1 state due to relativistic effects, and roentgenium may do so as well:[2] the electron affinity of roentgenium is expected to be around 1.6 eV (37 kcal/mol), significantly lower than gold's value of 2.3 eV (53 kcal/mol), so roentgenides may not be stable or even possible.
錀的电子亲和势比金低，就是说电负性比金低？金的电负性高不就是相对论效应导致的嘛，为什么相对论效应更强的錀没有延续该族电负性继续升高的趋势呢？我之前还期待錀会表现出很强的非金属性的，现在被打脸了= =
另外，113号元素uut也并未比铊的金属性更强，uut的第一电离能比铝还高
求大神解析
