玻意尔（Bohr）模型提出不久后，人们就发现原子中的电子比Bohr提出的模型要复杂得多。实验证实电子既有粒子的性质（质量）也有光的特性（波的特性）。因为它的两重性，电子不能被看作是在确定范围内绕核旋转的一种简单粒子，而且如Bohr所说的，如果电子高速运动，我们就不能确切地知道它的位臵。

PART TWO THE FUNDATIONS OF CHEMISTRY Unit7Chemical Bonds 化学键
There are approximately 100 chemical elements. 世界上大概有100种元素。
There are millions of chemical compound, and about 600000 new compounds are prepared every year.
现有数百万种化合物，而且每年有60万种新化合物被合成出来。
To form these compounds, atoms of different elements must be held together in specific combinations. be held together
in specific combinations 以特定的方式
为了合成这些化合物，不同种类的原子必须以特定方式结合在一起。
Chemical bonds are the forces that maintain these arrangements. That引导定语从句，修饰forces 化学键是保持这种结合状态的力。
Chemical bonding also plays a role in determining the state of matter.
plays a role 起作用
化学键同时在决定物质状态方面也起作用。
At room temperature, water is a liquid, carbon dioxide is a gas, and table salt is a solid because of differences in chemical bonding. 在室温下，水是液体，二氧化碳是气体，晶体盐是固体，是由于化学键的不同。
As scientists developed an understanding of the nature of chemical bonding, they gained the ability to manipulate the structure
