Answer:

Gaining electrons

Step-by-step explanation:

Anions are negatively charged ions.

When an atom gains some electrons then anions are formed.

As electrons are negatively charged so anions are also negatively charged ions.

Anions are attracted by the cathode which is positively charged electrode.
