2.不是所有的物质都有化学键结合。如:稀有气体。

3.不是所有的正四面体结构的物质键角为109。28, 如:白磷。


5.电解质溶液导电,电解抛光,等都是化学变化。

6.常见气体溶解度大小:NH3.>HCL>SO2>H2S>CL2>CO2

7.相对分子质量相近且等电子数,分子的极性越强,熔点沸点越高。如:CO>N2

8.有单质参加或生成的反应不一定为氧化还原反应。如:氧气与臭氧的转化。

9.氟元素既有氧化性也有还原性。 F-是F元素能失去电子具有还原性。

10.HCL ,SO3,NH3的水溶液可以导电,但是非电解质。

11.全部由非金属元素组成的物质可以使离子化合物。如:NH4CL。

12.ALCL3是共价化合物,熔化不能导电。

13.常见的阴离子在水溶液中的失去电子顺序:
