C) 35. D) 39 mass # = 19+ 20 = 139  Oct 17, 2018 - Potassium K Element 19 Mass Number: 39 Atomic weight: 39.098 g/mol Atomic number (Z): 19 Electrons: 19 Protons: 19 Neutrons: 20 Period: 4  Potassium (19K) has 26 known isotopes from 31K to 57K, with the exception of still-unknown 32K, as well as an unconfirmed report of 59K. Three of those isotopes occur naturally: the two stable forms 39K (93.3%) and 41K (6.7%), and a very Jun 16, 2018 19 protons, 20 neutrons and 18 electrons. Explanation: The atomic number gives the number of protons 19. p=19. The atomic mass is the sum  Z = atomic number = number of protons in the nucleus = number of electrons orbiting the nucleus; A = mass number Potassium K Z=19, A=39 Y Z=39, A= 89  Kids learn about the element potassium and its chemistry including atomic Potassium atoms have 19 electrons and 19 protons with one valence electron in the There are three isotopes of potassium that occur naturally: K-39, 40, and Number of neutrons = Mass number − Atomic number. Hence, number of neutrons in K atom = 39−19 = 20.

K 39 protons neutrons electrons

Potassium-39 is composed of 19 protons, 20 neutrons, and 19 electrons. Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons. Traces of K-40 are found in all potassium, and it is the most common radioisotope in the human body.

Each isotope has 19 protons and 19 electrons, but the number of neutrons vary In this video we’ll use the Periodic table and a few simple rules to find the protons, electrons, and neutrons for the element Potassium (K). From the Peri How many neutrons are present in an atom of K that has mass number = 39? mass number = number of protons + number of neutrons number of neutrons = = = change Isotopes • Not all atoms of the same element contain the same number of _____ (remember number of protons determines the identity of elements, NOT the number of neutrons).
