下列说法中正确的是(  )

A.原子核外电子排布式为1s2的原子与原子核外电子排布式为1s22s2的原子化学性质相似

B.Fe3+的最外层电子排布式为:3s23p63d5

C.基态铜原子的轨道表示式

D.基态碳原子的轨道表示式

答案

答案:B

核外电子排布为1s2的原子是He,核外电子排布是1s22s2的为铍(Be),He是惰性元素,Be是金属元素,显然化学性质不相似,A错;Fe的价电子排布为3d64s2,失去电子时先失最外层,再失次外层,失去2个电子变成Fe2+时最外层电子排布为3s23p63d6,失去3个电子变成Fe3+时,最外层电子排布为3s23p63d5,B正确;基态铜原子的轨道表示式,符合3d全充满时能量最低,即洪特规则特例,C错;基态碳原子是2s比2p轨道能量低,先填满2s再填2p,即,不存在半充满能量低的问题,D错。

Mo, the first Nobel winner in literature born and living in China, said he had trouble with the sudden publicity, which put a lot of pressure on him.

"I only hope to return to my writing desk as soon as possible, and I would also like to do well in society anonymously.(无名地)" Mo said. He was bothered by a large number of requests asking him to offer help that took advantage of his fame. " I was upset the first several days after the prize announcement, but then I realized the prize is just like a mirror that reflects various attitudes about my winning, and more, reflects the real me," Mo said. "I still consider myself an ordinary citizen who writes. And presenting quality works is my duty and best way of giving back to society. I'm no superstar," he emphasized(强调) several times.

Mo believes Chinese literature has achieved much in the past thirty years, and the driving force behind that is not the prize. Writers' creations should not be driven by awards, or criticism, or readers' expectations. Mo said he misunderstood the standards of the academy's selection before he visited Stockholm(斯德哥尔摩) to receive the prize in December.

"I thought they were judging the authors' personality or political features, then I learned the sole standard of their selection is literature itself, which is also deeply based in the Swedish people's long-established practice of reading a large number of books," Mo said.

During the forum, established Chinese and Australian writers discussed subjects as diverse as tradition and modernity, the local and the universe and cultural inclusiveness. And they will also read works to each other and the readers. The writers communication will further promote(推动) Chinese writers to a global audience.

Australian Ambassador(大使) to China Frances Adamson agreed. "It's a milestone (驱动)of literary exchanges between the two countries, who are longtime friends," Adamson said.
