An atom's nucleus has a positive charge.

原子核带正荷。

The fundamental charges are a positive charge and a negative charge.

荷是正荷和负荷。

At the center of an atom is its nucleus which has a positive electric charge.

原子的中心是它的原子核，它带有正荷。

Protons have a positive electric charge, electrons a negative charge, and neutrons are neutral.

质子带正荷，子带负荷，中子则是中性的。

By applying a positive charge to the control electrode, it would permit the flow of electrons as before.

通过向控制极施加正荷使得子可以流动。

Nature balances things out with equal positive charges somewhere else.

Bees, on the other hand, develop a slight positive charge just by flying through the air.

另一边，蜜蜂通过在空中飞翔获得微弱的正荷。

The short and sweet of it is that the waste molecules lose electrons and become more positively charged.

简单来说，废物分子失去子，带更多正荷。

A positron for example is just like an electron but it has positive charge.

比如一个正子，就是一个子，但是带有一个单位正荷。

Electrons whiz around the nucleus, their negative charge attracted by the protons' positive charge.

So this is a negative charge and then you have positive charges in the center.

所以这是一个负荷，然后你在中心有正荷。

These, despite being mutually repulsive because they are positively charged, are held together by a phenomenon called the strong nuclear force.

虽然质子之间因带正荷而相互排斥，但被强核力聚集在一起。

Sodium lost an electron, so it ends up with a positive formal charge, like that.

钠失去了一个子，所以它最终带有正荷，就像那样。
