z z So the charge is actually just equal to z, +2e we can write plus 2, or you can write plus 2 e, e he charge on an electron.
是多少呢？是的。，What，is，z？，Yup，，so，it’s，plus，2。,它是+2所以电荷量实际上仅仅等于，我们可以写+2或者你可以写，仅仅指一个电子电荷量，e，just，means，the，absolute，value，of，t,的绝对值。
So, an electron has a charge of negative e, we've written here and the nucleus has a charge of positive e.
我们写在这，原子核带正e的电荷，我们看到作用力。
