我想象它们的样子,通过共价键结合的分子链。
I'm imagining something like, covalently bonded chains that have links between them.
当我们刚开始介绍共价键的时候,我们说过电子是被共用的,但是共用却不一定是均等的。
So as we said when we first introduced covalent bonds, it's a sharing of electrons, but it's not always an equal sharing.
Likewise, the element that is a good electron acceptor in an electron transfer reaction is going to be the element that is going to hog the electrons in a covalent bond.
同样的,这个元素在一个电子转移反应中,是个很好的受赠者它将成为在共价电子,中吸引电子的元素。
He introduced the concept of electronegativity which was a measure, therefore, it is quantitative, of the atom's ability to attract electrons within a covalent bond and developed a scale of electronegativity.
他引入了电负性这一概念,一个反映着原子在成共价键时吸引电子的能力的数据标度,因此这是数量上的,在共价电子中,电子原子能吸引电子,并发展为一定规模的电负性。
Well, if it is a good electron donor in an electron transfer reaction, if the same element finds itself in a covalent bond, it is going to be a good electron donor, although it is not full transfer.
如果它是一个在电子反应中,的好捐赠者,如果相同电子发现他在共价电子里,它将成为一个好的捐赠者,虽然没有完全转换。
