An electron has a negative charge,a proton has a positive charge.

带负,质带正。

The positive pole carries a positive charge while the negative pole does a negative charge.

正极带正, 负极带负。

Electrons are negatively charged with electricity,protons are positively charged.

是带负,质是带正。

Electrons are negatively charged with electricity.

带负。
