大部分物体都是电荷平衡的——含等量的电子和质子。
Most things are balanced - with equal numbers of electrons and protons.
如果是原子质量一定,而电子很小,那么带正电荷的部分几乎占据了全部质量。
If the atom is fixed mass, and the electron is tiny, it must be the positives have all the mass.
它们也会在相邻部分利用氢键和电荷的相互作用搭起桥梁。
They also form Bridges between neighboring sections by hydrogen bonds and charge interactions.
We'll get to oxidation number in the second half of this course, but it's not in any way the same idea as formal charge.
我们会在课程的后半部分讲到氧化数,但它和形式电荷完全不是同一个概念。
