Which of the following groups is characterized by both a high ionization energy and an electron affinity that is close to zero?
Periodic Trends AQ2
A. Alkali metals (group 1)
B. Transition metals (groups 3-12)
C. Halogens (group 17)
D. Noble gases (group 18)

Respuesta :

Answer:

D

Explanation:

Noble gases do not want to lose electrons because they have a full outer shell, so their ionization energy will be very high. Their electron affinity is close to zero because they also do not want to attract electrons to their cell since they already have all 8 valence electrons.
