Solution
It seems like your question is incomplete. However, I can provide some general information based on what you've asked.
Group 1 elements are known as alkali metals. As you go down the group (from Lithium to Francium), the hardness of these elements generally decreases. This is due to the increasing atomic size and decreasing effective nuclear charge, which makes the outermost electron more easily removable.
Potassium is the fourth element in Group 1, coming after Lithium, Sodium, and Potassium. Therefore, its hardness is likely to be less than these three elements but more than the elements below it in the group (Rubidium, Cesium, and Francium).
Without specific hardness values for the elements surrounding Potassium, it's difficult to predict an exact hardness value for Potassium. However, based on the trend in Group 1, we can predict that Potassium is less hard than Lithium, Sodium, and Potassium but harder than Rubidium, Cesium, and Francium.
