What you see is that the radius changes with atomic number for constant electron number.

对于等电子数的粒子， 离子半径随着，原子数的变化而变化。

The electron number density does not strictly obey exponential damping law in a long period.

电子数密度在很长的一段时间内不遵循指数衰减规律。

We analysed the phenomenon based on structure. With its electron number creasing, organic compounds' color deepens.

我们从结构上进行分析，随着有机化合物共轭电子数增多，其颜色加深。

z So in our first case, our first extreme case, would be that the z effective that is felt by electron number 1, is going to be plus 1.

被1号电子感知到的有效的，是+1所以,我们所能做的是计算出，我们从这个。

So, electron promotion does not happen in terms of nitrogen, because it would not increased our number of unpaired electrons.

这里对于氮原子不会有电子激发，因为这不会增加,未配对电子的数目。

Using the underground Sudbury neutrino detector, an international group of researchers has been able to determine that the observed number of electron-neutrinos is only a fraction of the total number emitted from the Sun - clear evidence that the particles change type en route to Earth.

Because these reactions are understood, it has been possible to estimate the number of electron-neutrinos that should emerge from our star.

It levelled out, as predicted, at around half the amount expected if no change was taking place, while the number of electron neutrinos was unchanged.
