读下表完成填空

元素符号ABCD
该元素的某

微粒结构图

①______元素在元素周期表中位于C元素的后边.

②一般难形成化合物的元素是______.

③______是属于阴离子,______元素的化合价通常显+1价.

答案

由表中微粒结构示意图可知:①因为原子序数=核内质子数,所以在元素周期表中质子数小的在质子数大的前面,故D应该在C元素的后面;

②一般难形成化合物的元素是具有稳定结构,四种元素中C为氖元素,是稀有气体元素化学性质很不活泼,一般不宜形成化合物;

③阴离子是核外电子数大于核内质子数的微粒,分析四种微粒可知B是阴离子;A为氢元素,最外层电子为1,化学反应中易失去1个电子而带一个单位的正电荷,化合价一般为+1价;

故答案为:①D;②C,③B;A;

Rachael lives in Wisconsin and has lived there all her life. She is just an average girl; at first when you are around her, she seems to be very shy. If you get to know her, she’ll start to open up but always keep things to herself.

Sports are something that keeps her going, a way to release stress. Usually, you will see Rachael out with friends or just sitting down reading a good book. She takes pride in the fact that she can read a whole book in one day, and that she still doesn’t consider herself a bookworm.

Rachael wants to be two completely different people in her life. A communication journalist for one, she has always wanted to be that person. The second possible career would be lawyer. It’s a huge goal, and one day you’ll see her doing something she loves.

Influenced by her parents, Rachael enjoys listening to all kinds of music. Rarely, if ever, do you see her without some sort of music. Every morning you can see Rachael in her bathroom getting ready for school with her player at maximum volume(音量).Her parents always get mad at her about that, but she can’t hear them anyway over the music.
