Potassium (K) and nickel (Ni) are both elements found in the same period (the fourth period) of the periodic table. This means they share the same principal energy level (n=4) in their electronic configurations. However, potassium is an alkali metal (Group 1) and nickel is a transition metal (Group 10), so they have different chemical properties and behaviors.
Here are a few things they have in common:
- Period: Both are in Period 4 of the periodic table.
- Electron Shells: They have the same number of electron shells (four).
- Metallic Properties: Both are metals, though they have different properties and reactivities.
- Conductivity: Both can conduct electricity, although they do so to different extents and in different ways due to their differing metallic bonds and structures.
Despite these similarities, the differences in their chemical properties and reactivity are significant due to their positions in the periodic table.
