So this is the energy of a single ionic bond.

这就是单离子键的能量。

Electrovalence: valence characterized by the transfer of electrons from atoms of one element to atoms of another during the formation of an ionic bond between the atoms.

电价：在原子间形成离子键的过程中，由电子从一种元素的原子转移到另一种元素的原子所表示的价。

Ionic bonds are usually studied with the help of electro-statics, whereby the bond energy is calculated by Born's Formula with an error about 10% from the experimental data.

离子键一般用静电理论来描述，键能用波恩公式计算，误差约为10％左右。

youdao

He said that the percent ionic character, and this is within a bond, not for a compound, for a covalent bond.

他提到离子百分数，是指一根键中，并非一个分子中。

The Born-Haber cycle was designed to allow us to calculate the energetics of, in particular,the ionic bond.

伯恩哈勃循环,可以让我们计算能量，特别是离子键的。

Now, last day, we looked at the energetics of the ionic bond, right?

昨天，我们讲的是离子键的热力学，对么？
