下列四种元素中，单质氧化性最强的是 …（） A．原子最外层有5个电子的第2周期元

英国化学家道尔顿在他的著作《化学哲学新体系》中提出了下列有关物质构成的观点：“一切物质都是由大量的. 极其微小的粒子（原子）构成的，这些粒子间通过引力作用而相互结合成物质。人们不可能创造出新原子，也不可能将原子进一步分割。人们所实现的只能把结合在一起的原子分开或将原子重新组合起来。”这一学说对化学学科的发展起到了巨大的作用。但是，当阿伏伽德罗提出了分子概念后，有人对道尔顿的上述观点作出了如下修正：

①“一切物质”应该为“有些物质”；

②“人们所实现的变化”应限定为“化学变化，不包括其他变化”；

③“不能创造或分裂原子”应为“用何种方法都不能创造或分裂原子”；

④原子是构成物质的最小粒子。

Jessica Alba rebelled(叛离) from her "strict" parents when she was just five. The 29-year-old actress admits her Catholic(天主教) education made her want to "break away" from her mother Catherine and father Mark.

She explained: "It's always been weird(古怪的) because I grew up in a very traditional, Catholic household. My parents were very strict but I broke away from that at an early age. I was a feminist（女权主义者） when I was five. These days, I am much more independent but I still respect their beliefs."

As Jessica has grown older she has learnt to accept her parents' views, but still considers herself an independent woman.

In her latest film 'Machete' Jessica gets to stab(刺) a love rival in the eye with her stiletto heels（鞋后跟）, something she thoroughly enjoyed.

She said: "Walking in 3in heels wasn't as much fun as putting one in someone's eye. It was 104 degrees where we were shooting in Texas and they were not comfortable."

Jessica - who has a two-year-old daughter Honor with husband Cash Warren - is regularly referred to as one of the world's most beautiful women, but she doesn't think of herself as "sexy".

She added in an interview with the Metro newspaper: "I don't really pay attention to that sexy image. It just goes with the character in the movie. At the end of the day, it's all a part of selling a product."
