That is potassium which occurs naturally in three isotopes, 39K, 40K and 41K. The numbers of neutrons in the nuclei of atoms of these isotopes are 20, 21 and 22 respectively. Please see the link.
Potassium (K) typically has 19 neutrons in its nucleus. Potassium-40 is a radioactive isotope with 21 neutrons in its nucleus.
A potassium-37 (K-37) atom typically has 20 neutrons in its nucleus. This is because the number of neutrons is calculated by subtracting the atomic number (which is 19 for potassium) from the mass number (which is 37 for K-37).
The atomic number of potassium is 19. So there are 19 protons, 19 electrons. In K-40 isotope, there are 21 neutrons.
Potassium has 20 neutrons in its most abundant isotope, potassium-39.
Potassium (K) Has the same number of electrons as protons therefore it has 19 electrons. To find the number of neutrons you take the mass of the element minus the number of protons so 39-19=20. so there are 20 neutrons in potassium.
It has 20 neutrons.
Potassium-40 (K-40) has 19 protons and 21 neutrons.
Potassium (K) typically has 19 neutrons in its nucleus. Potassium-40 is a radioactive isotope with 21 neutrons in its nucleus.
19 electrons, 19 protons and 20 neutrons
Potassium-41 has 19 electrons and protons and 22 neutrons.
A potassium-37 (K-37) atom typically has 20 neutrons in its nucleus. This is because the number of neutrons is calculated by subtracting the atomic number (which is 19 for potassium) from the mass number (which is 37 for K-37).
The nucleus of an atom K-42 contains 19 protons and 23 neutrons. This is because K (potassium) has 19 protons in its nucleus, and the isotope K-42 has an atomic mass of 42, which means it must have 23 neutrons to account for the mass.
The mass number of Potassium is 39 which means it has 20 neutrons.
Potassium (K) has 20 neutrons in its most stable isotope (K-39), while cobalt (Co) has 27 neutrons in its most stable isotope (Co-59). Therefore, cobalt has more neutrons than potassium.
The atomic number of potassium is 19. So there are 19 protons, 19 electrons. In K-40 isotope, there are 21 neutrons.
Potassium has 20 neutrons in its most abundant isotope, potassium-39.
The correct symbol for the isotope of potassium with 22 neutrons is K-41. The number after the element symbol represents the atomic mass, which is the sum of protons and neutrons in the nucleus. In this case, potassium has 19 protons and 22 neutrons, resulting in an atomic mass of 41.
