a. a metallic element with a large atomic radius, high ionization energy, and highly reactive.

b. a metallic element with a large atomic radius, low ionization energy, and highly reactive.

c. a metallic element with a large atomic radius, low ionization energy, but relatively unreactive.

d. a nonmetallic element with a large stomic radius, low ionization energy, and highly reactive.

Answer 1

Answer: A

Explanation: element 119, ununennium, is highly reactive and has high ionization energy, leave A as the only answer.
