I apologize for the incorrect response. Sodium (Na) and potassium (K) are actually in the same group on the periodic table because they have similar properties and react in a similar manner. This includes their tendency to lose one electron and form a +1 cation in chemical reactions. Therefore, the correct answer is indeed D: They have similar reactivity.

Answer 4

Okay, but are you sure sure?

Answer 5

Yes, I am sure that the correct answer is D: They have similar reactivity. Sodium and potassium are both alkali metals and are located in Group 1 of the periodic table. Being in the same group means that they have similar properties and share similar trends in their chemical behavior.
