Question

which periodic trend quantifies the amount of energy required to remove an electron from a neutral, gaseous atom? answer: a atomic radius b ionization energy c ionic radius d electron affinity e electronegativity

Explanation:

Ionization energy is defined as the energy required to remove an electron from a neutral, gaseous atom. Atomic radius is the measure of the size of an atom. Ionic radius is the measure of the size of an ion. Electron affinity is the energy change when an electron is added to a neutral atom. Electronegativity is the tendency of an atom to attract electrons in a chemical bond.

Answer:

B. Ionization energy
