Step 1
: Refer to the periodic table and locate potassium (K), which is in group 1 (excluding the noble gases group).

Step 2
: The number of valence electrons in an element is equal to the group number in which the element is located in the periodic table.

This is a general rule for main group elements.

Final Answer

Potassium (K) has 1 valence electron.
