D Hawking has left much for Chinese to think about. British physicist Stephen hawking, possible the world’s most famous scientist after Albert Einstein, gave lectures in Zhejiang and Beijing in August. An illness left him unable to move any part of his body except for three fingers. But his continuing efforts in the field of science have made many young people take him as their idol(偶像). His books, such as A Brief History of Time, become bestsellers in Chinese bookstores. “Hawking helps people enlarge their horizons and become interested in science,” said Pan Yunhe, president of法国一家公司研发出一种比锂电池成本更低、寿命更长、充电速度更快的钠离子电池,该电池的负极材料为Na2Co2TeO6(制备原料为Na2CO3、Co3O4和TeO2),电解液为NaClO4的碳酸丙烯酯溶液。回答下列问题:(1)C、O、Cl三种元素电负性由大到小的顺序为________________________。(2)基态Na原子中,核外电子占据的原子轨道总数为______,Te属于元素周期表中______区元素,其基态原子的价电子排布式为______________________。(3)CO32-的空间构型为___________________,碳酸丙烯酯的结构简式如图所示,其中碳原子的杂化轨道类型为____________,1mol碳酸丙烯酯中σ键的数目为_________________。(4)Na和O形成的离子化合物的晶胞结构如图所示,晶胞中O的配位数为____________,该晶胞的密度为ρg/cm3,阿伏加德罗常数的值为NA,则Na与O之间的最短距离为____________cm(用含有ρ、NA的代数式表示)。
