Polonium (Po) has the highest first electron affinity among the given options. Electron affinity generally increases across a period in the periodic table because the nuclear charge increases, attracting electrons more strongly. Polonium is to the right of francium (Fr), radium (Ra), and radon (Rn) in the periodic table, indicating it would have a higher electron affinity than the other elements listed.
