B)Bromine is bigger than potassium
C)Bromine has a greater ionization energy than potassium does
D)Bromine is a liquid and potassium is a solid
E)Bromine is more metallic than potassium

Question

Quizplus · Accepted Answer

Bromine has a higher electron affinity than potassium, meaning it has a greater tendency to gain electrons and become an anion. This is because bromine has a partially filled p orbital, making it highly reactive and more likely to form a negative ion. Potassium, on the other hand, has a filled valence electron shell and is more likely to lose an electron and become a cation.
