问题 填空题

下表为长式周期表的一部分,其中的编号代表对应的元素。

请回答下列问题

(1)表中属于d区的元素是________________(填编号)。

(2)科学发现,②、④、⑨三种元素的原子形成的晶体具有超导性,其晶胞的结构特点如图(图中②、④、⑨分别位于晶胞的体心、顶点、面心),则该化合物的化学式为_________________(用对应的元素符号表示)。

(3)元素②的一种氢化物是重要的化工原料,常把该氢化物的产量作为衡量石油化工发展水平的标志。有关该氢化物分子的说法正确的是__________________。

A.分子中含有氢键

B.属于非极性分子

C.含有4个σ键和1个π键

D.该氢化物分子中,②原子采用sp2杂化

(4)某元素的特征电子排布式为nsnnpn+1,该元素原子的核外最外层电子的孤对电子数为_________;该元素与元素①形成的分子X构形为______________;X在①与③形成的分子Y中的溶解度很大,其主要原因是__________________________。

(5)A、B均为短周期金属元素。依据下表数据,写出B原子的电子排布式:__________________

(6)过渡金属离子与水分子形成的配合物是否有颜色,与其d轨道电子排布有关。一般而言,为d0

d10排布时,无颜色;为d1~d9排布时,有颜色,如[Co(H2O)6]2+显粉红色。据此判断,[Mn(H2O)6]2+

_____________颜色(填“无”或“有”)。

答案

(1)⑨

(2)MgCNi3或CMgNi3

(3)BD

(4)1;三角锥形;X和Y都是极性分子(且能形成氢键),根据相似相溶原理,极性分子易溶于极性溶剂中

(5)1s22s22p63s2

(6)有

      Last week, all the teachers and students of our school watched a special performance by some disabled
(残疾的) people. The first program was a dance named "The light of life". To my surprise, all the dancers
had lost one of their legs. As they were performing, I could see how they had to face so many difficulties.
However, they showed us many wonderful programs. From these programs, I could see how lively their
minds were.
     The two persons who came out next shocked us all. The first one was a singer. He was very young but
unfortunately he had lost both of his hands in a big fire. The song he brought us was "Late Autumn" and he
sang it in such a low and sweet voice. Though it was warm spring, I felt a little cold when I heard the song
as if it was really late autumn. "How much love and feeling is hidden in my heart? I wish to hold your hands
again. " Hearing this, I couldn't keep back my tears.
     The other one was also a young man. He lost both of his arms when he was six. From then on, his feet
became his "hands". However, he could manage a number of things with his feet. What moved us most was
his feet writing. The two words "Flying High" expressed his wishes.
     "If your wings are gone, your heart can still fly," said Zhang Haidi, a disabled writer. 
     In the world, there are many disabled people, yet most of them don't give in (屈服). They have strong
wishes and beautiful dreams. Just as Zhang Haidi said they could fly.
     Disability doesn't mean complete failure. Once you try hard, miracles (奇迹) will happen sooner or later.
I believe where there is a will,there is a way.
