原子是电中性的。

We knew that the atom was electrically neutral.

youdao

任何原子的质子数量与电子数量相等，因此是电中性的。

In any atom, the number of protons is equal to the number of electrons, and hence it is electrically neutral.

youdao

当质子总数等于电子的总数时，这个物体就整体来说是电中性的。

When the total number of protons equals the total number of electrons, the body as a whole is electrically neutral.

youdao

The molecule is net neutral, but this right end is a little bit more negative and the left end is a little bit more positive.

这分子是电中性的，但右边要带一点负电荷,而左边要带一点正电荷。

And by here, I mean it's net neutral, but the electron deficiency.

我的意思它是电中性的，只是有些缺电子。
