mixed-valence charge transfer 价态电荷转移
oxygen valence charge 氧原子价态
valence charge density 价电荷密度
So in our first structure, we would find for the nitrogen we have a formal charge 5 minus 4 minus 2, because we're starting with 5 valence electrons, so that is a formal charge of minus 1.
那么在我们的第一个结构中,我们发现氮的形式电荷量是五减去四4,再减去二,因为我们开始有五个价电子,因此它的形式电荷量是负一。
So, if we want to figure out the formal charge on the carbon, we need to take the number of valence electrons, so that's 4. We need to subtract the lone pair, what number is that? It's 2.
如果我们想算出碳原子的形式电荷,我们需要将价电子的个数,也就是四,减去孤对电子的个数,它是多少?是二。
Hole - Similar to a positive charge, this is caused by the absence of a valence electron.
空穴-和正电荷类似,是由缺少价电子引起的。
For the carbon, we start with 4 valence electrons, we have 0 lone pair electrons minus 4, and we end up with a formal charge of 0.
对于碳,我们从四个价电子开始,我们有零个孤对电子,再减去四,最终我们有零个形式电荷。
So, if we want to figure out the formal charge on the carbon, we need to take the number of valence electrons, so that's 4. We need to subtract the lone pair, what number is that? It's 2.
如果我们想算出碳原子的形式电荷,我们需要将价电子的个数,也就是四,减去孤对电子的个数,它是多少?是二。
This is the valence, the charge on the cation times I will common factor this.
这是价电子,阳离子的电荷乘以,共同因子。
