The correct response is:
**They have the same number of electron shells.**
Potassium (K) and nickel (Ni) are in the same row (period) of the periodic table, which means they have the same number of electron shells. Potassium is in Group 1 and nickel is in Group 10, so they do not share similar reactivity or the same number of valence electrons. They also have different physical properties.
