The result of thermionic emission is a(n):

Explanation:
When a filament is heated, electrons are released into the surrounding vacuum. These emitted electrons create a region of negative charge around the filament, known as an electron cloud or space-charge. This cloud forms the immediate result of thermionic emission before the electrons are attracted to the anode to form a current. The other options describe photons or a single recoil electron, which are not produced by thermionic emission.
