Atoms that have become negatively charged by gaining extra electrons are called anions anodes cations cathodes

Anions

Explanation:

Anions : Anions are defined as the atoms or the radicals. Atoms that have become negatively charged by gaining extra electrons are anions. For example, bromide ion (Br⁻), chloride ion (Cl⁻).

Anodes : The positively charged electrode by which an electron leave a device is called an anode.

Cations : They are the positively charged particle. For example silver ion (Ag⁺).

Cathodes : The negatively charged electrode by which an electron enter an device is called an cathodes.

Hence, the correct option is (a) " anions ".

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
