Fission refers to the process where one nucleus splits into two roughly equal nuclei.

裂变是指一个子核分裂成两个大致相等子核过程。

An atom's nucleus has a positive charge.

子核带正荷。

Streaming out of a nuclear reactor of course!

当然得出现一个子核反应！

In fission, the splitting of a nucleus generates energy.

在裂变中，子核分裂产生能量。

The nucleus and the electrons going around the atom.
