Detailed explanation-1: -Any atom that has 19 protons is a potassium (K) atom. Which statement best describes what would happen if a proton was added to potassium atom? The atom would have a negative charge.
Detailed explanation-2: -The atomic number is how the elements are ordered on the periodic table, which for potassium is 19. This means that this isotope of potassium has 19 protons and 20 neutrons. The mass number is the sum of these two: 19 + 20 = (d). 39.
Detailed explanation-3: -The most abundant isotope of potassium contains 20 neutrons. All isotopes of potassium will have the same number of protons inside their nucleus, i.e. 19 protons.
Detailed explanation-4: -Potassium is a chemical element with symbol K and atomic number 19. Classified as an alkali metal, Potassium is a solid at room temperature.
