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。

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.

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。
