# how many neutrons does potassium have

1)An ion of potassium has a charge of +1. Home. Booster Classes. How many neutrons does hydrogen have? Study Guides. Atomic Mass: 39.0983 amu. How many neutrons does mercury have? Rounded down, it is 39 for potassium. 80. 0. How many protons does helium have? Chemistry Q&A Library Please help questions! Blurtit. Homework Help. By plugging in these values, we can therefore deduce that:Atomic Number (19) = 19 ProtonsAtomic Number (39.0983) = 19 Protons + Number of NeutronsNumber of Neutrons = 39.0983 - 19 = 20.0983 ≈ 20 In essence, potassium has 20 neutrons. How many protons does platinum have? Your dashboard and recommendations. ----protons -----neutrons --- … Figure 2.1.2: How many neutrons do (K) potassium-39 and potassium-40 have, respectively? Basic Information. Personalized courses, with or without credits. Clearly, there are 19. How many protons does mercury have? How many neutrons does platinum have… Number of Neutrons: 20. Potassium-39 has twenty neutrons. Potassium Chloride (KCl) Potassium Fluoride (PF) Potassium Iodide (KI) Interesting facts: It was the first metal to be isolated using electrolysis. Potassium-40 has twenty one neutrons. How many neutrons does potassium have? People rarely look at the world around them in atomic terms, unless perhaps they are scientists. So for potassium, 19 taken away from 39 leaves 20 neutrons. Potassium is element #19, that means K has 19 protons. 3.7 million tough questions answered. Because potassium has 3 isotopes, then we have to calculate for the different atomic weights of the isotopes: Potassium-39- It has 19 protons and atomic mass is 39. By subtracting the number of protons or electrons from that number (in this case, 19), the total remaining is the number of neutrons. And how did I know? Name: Potassium. 121. # neutrons = 22. Switch to. How many protons and electrons does this ion have? Mass number = # protons + # neutrons. It burns with a violet flame. Potassium-40- It has 19 protons and atomic mass is 40. 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. Hence, number of neutrons is 40 - … 41 = 19 + # neutrons. 117. We know that potassium has an atomic number of 19 and an atomic mass of 39.0983 amu. ----protons __-_electrons -----neutrons 2)An ion of oxygen has a charge of -2. how many protons, neutrons, and electrons does the atom have? So to get the number of neutrons, you take the average mass of 39 and subtract the number of protons and that leaves you with 20 neutrons. The element in question is potassium, the 19 symbolising the atomic number, the number of protons. It catches fire when exposed to water. Other examples of isotopes: C-12, C is #6, it … Hence, number of neutrons is 39 - 19 which is 20. 2. 78. Hence the number of neutrons is the atomic mass minus the atomic number, 39 - … Get the detailed answer: How many neutrons do (K) potassium 39 and potassium 40 have, respectively? Since potassium has 19 electrons you know that it then has 19 protons because there is no charge change. Well, how many protons are in the [math]^{40}K[/math] isotope?
