Final Answer
In a neutral atom of potassium (K): - Protons: 19 - Electrons: 19 - Neutrons: 20 Explanation: The number of protons is determined by the atomic number (19), which also equals the number of electrons in a neutral atom. The number of neutrons is calculated by subtracting the atomic number from the mass number of the most common isotope (39 - 19 = 20).
