What is the factor that affects how easily an electron can be removed from an atom?

Asurrounding atoms.
Btemperature of the environment.
Csize of the atom.
Dstructure of the atom

Verified Answer :

I think the correct answer among the choices listed above is option D. It is the structure of the atom that is theĀ factor that affects how easily an electron can be removed from an atom. This is because having a stronger structure would mean that electrons have a strong attraction to the atom and it would be harder to remove the electrons.
