Relevance. Chlorine-35 accounts for 76% of the natural abundance of the element, with chlorine-37 making up the other 24% of the element. In its nucleus and its most … The ground state is the most stable energy state for the electrons K means potassium.

Abbreviation= Ti Mass=48 Protons= 22 Neutrons= 26 Electrons= 22. Vanadium. Abbreviation= V Mass=51 Protons= 23 Neutrons= 28 2020-05-26 · So for your question, the Periodic Table tells us that potassium has an Atomic Number of 19, so there are 19 protons and 19 electrons. The Periodic Table tells us that potassium has an Atomic Mass of ≈39. So there are 39 - 19 = 20 neutrons. Protons and electrons can be combined into neutrons. How many protons electrons and neutrons does K-39 have?

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. Name: Potassium Symbol: K Atomic Number: 19 Atomic Mass: 39.0983 amu Melting Point: 63.65 °C (336.8 K, 146.57 °F) Boiling Point: 774.0 °C (1047.15 K, 1425.2 °F) Number of Protons/Electrons: 19 Number of Neutrons: 20 Classification: Alkali Metal Crystal Structure: Cubic Density @ 293 K: 0.862 g/cm 3 Color: silvery Atomic Structure Each isotope has 19 protons and 19 electrons, but the number of neutrons vary. Potassium-39 has 20 neutrons, Potassium-40 has 21 neutrons and Potassium-41 has 22 neutrons. 19 protons, 20 neutrons and 18 electrons. The atomic number gives the number of protons 19 p= 19 The atomic mass is the sum of the protons and neutrons p + n = 39 p= 19 put p into the equation and solve for n the neutrons. 19 + n = 39 Subtract 19 from both sides 19 -19 + n = 39 -19 n = 20 The number of electrons equals the number of protons in a neutral atom.
