To determine which element has the smallest atomic radius among Germanium (Ge), Gallium (Ga), Potassium (K), and Calcium (Ca), we can compare their atomic radii values.
Here are the atomic radii of these elements:
- Germanium (Ge): 122 picometers
- Gallium (Ga): 135 picometers
- Potassium (K): 196 picometers
- Calcium (Ca): 174 picometers
Now, let's compare these values:
- Ge (Germanium) has an atomic radius of 122 picometers.
- Ga (Gallium) has an atomic radius of 135 picometers.
- K (Potassium) has an atomic radius of 196 picometers.
- Ca (Calcium) has an atomic radius of 174 picometers.
From the above values, we see that Germanium (Ge) has the smallest atomic radius at 122 picometers.
Therefore, the element with the smallest atomic radius among the given elements is Germanium (Ge).
