第一主族的金属元素不能互相置换,只能置换氢.
因为,放入水溶液中置换水中的氢,而不和金属离子反应
第二主族的金属元素仅铍镁,可以置换,其他金属不能置换的原因同上
第三主族的元素除硼外,一般可以置换
硼是较不活泼非金属
第四主族的元素不能置换
原因都是不活泼非金属,
第五主族可以置换,但反应条件要高温高压
第六主族上面换下面,
活泼换不活泼
第七主族上面换下面

Ocean from float ten thousand mountain green weeds here
We roam about at pleasure heartily a radiant bosom to embrace here
The strong breeze rises us to face bluish green wave of wave greatly
The snowflake dances in the wind our underwater 嬉 to make

上联缺“六”,下联缺“九”,因“六”与“肉”、“九”与“酒”谐音,合起来就是“缺肉少酒”,横批是“吝啬”.

按照过去的意思应该是“缺酒(九)少肉(六) ”,不过“六”解释为“肉”有些牵强,两个字不能谐音,现在有人将它解释为：缺酒少妞!

一加一等于二——错不了
一二三四五六七——忘(王)八
三加二减五——等于零
八分之七———七上八下

1+2+3+3+2+1+1+2+3+4+5+6+7+7+8+8+7+9+10+11
=1+2+3+4+5+6+7+8+9+10+11+6+6+7+7+8
=66+34=100

一二三四五六七：忘（王）八
孝悌忠信礼仪廉：无耻

一二三四五六七
孝悌忠信礼义廉
清朝,临池王半朝为显示他家有文有武,建造了一座功德牌坊,请蒲松龄题副楹联.蒲松龄知道：这王半朝排行第八,为人狡诈霸道,人称“王八”.就写了“三朝元老”四字,然后写下一副楹联：“一二三四五六七,孝悌忠信礼义廉.”王半朝以为这是称颂五府的,就请有名的工匠把这副楹联刻在牌坊上.大家仔细一琢磨,不禁大笑起来.原来,上联隐“八”,即忘（王）八；下联隐“耻”,即“无耻”.整个楹联的意思是：三朝元老,王八无耻.

（1）第六、七周期在第ⅢB族中出现了镧系、锕系，每个系的一个空格包含了15种元素，第六、七周期比第四、五周期多了14种元素，
故答案为：第六、七周期在第ⅢB族中出现了镧系、锕系，每个系的一个空格包含了15种元素；
（2）第六、七周期在第ⅢB族中出现了镧系、锕系，每个系的一个空格包含了15种元素，故ⅢB族含有元素最低；碳元素形成有机物，化合物种类最多，处于第ⅣA，
故答案为：第ⅢB；第ⅣA；
（3）观察每一周期的元素数发现，它们都是偶数，规律如下：

2×4²从中可发现，它们遵循2×n²，除第1周期外，重复一次，故第8周期含有的元素种数为：2×5²=50，
故选：C；
（4）A．镭是周期表第7周期IIA族的元素，最外层有2个电子，则在化合物中呈现+2价，故A正确；
B．Ca、Ba为金属性很强的元素，同主族元素从上到下元素的金属性逐渐增强，则镭对应的氢氧化物具有强碱性，故B错误；
C．镭的金属性比Ca、Ba等强，能与水发生剧烈反应，放出氢气，故C正确；
D．已知碳酸镁、碳酸钙难溶于水，根据同主族元素对应单质、化合物的性质的相似性可知，镭的碳酸盐难溶于水，故D正确，
故选：B．
