Step 1: The atomic number of potassium (K) is 19.
The atomic number is the number of protons in an atom's nucleus, which is also equal to the number of electrons in a neutral atom.
Step 2: Valence electrons are the outermost electrons in an atom that can participate in the formation of chemical bonds with other atoms.
For neutral atoms, the number of valence electrons is equal to the element's group number in the periodic table.
Final Answer
A neutral atom of potassium (K) has 1 valence electron.
