Ionization energy vs. electron affinity

Postby Jessa Maheras 4F » Sun Oct 27, 2019 7:32 pm

I'm having trouble understanding the difference between ionization energy and electron affinity! What types of questions will be asked about these concepts?

I don't exactly know what questions will be asked about the two but they are different. Ionization energy refers to the amount of energy necessary to remove the outermost electron of an atom or molecule. Electron affinity refers to the amount of energy necessary for a neutral ion to gain an electron and become negatively charged. Both ionization energy and electron affinity increase as you go up and right on the periodic table.
