ANSWERS. 34 protons, 44 Aug 9, 2018 We can take atomic number (19) and subtract it from the rounded atomic weight ( 39). That leaves us with 20 which is the number of neutrons a Aug 15, 2020 How many protons, neutrons, and electrons are present in atoms with the following characteristics? Units of measure have been defined for Explain, in terms of both electrons and energy, how the bright-line spectrum of an element is Explain, in terms of protons and neutrons, why U-235 Explain, in terms of subatomic particles, why K-37 and K-42 are isotopes of potassi The atomic mass number is the number of protons plus neutrons in the an atomic number of 20 but there are three isotopes of calcium - 39, 40, and 42.

Calculate the number of proton, neutrons and electrons in `._(19)^(39) K` . Indicate the number of electrons, protons and neutrons in the element .

Protons and electrons can be combined into neutrons. K means potassium. If you Google “potassium” you will find that it has atomic number [math]Z=19[/math], which means that it has 19 protons in the nucleus. The superscript “+” means that you’re talking about the positive ion of potassium, which mea Tableau périodique de classfication des éléments de Mendeleiev en ligne. Here is the generic procedure. Step 1: For the number of protons, it is equal to the atomic number. You can look up the atomic number for any element on the Periodic Table of the Elements, or any Table of the Elements.

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. Mass number is the sum of the protons and neutrons in the nucleus of a specific isotope of an atom. Answer and Explanation: {eq}\rm ^{39}_{19}K {/eq} has 19 protons and 20 neutrons.
