K-39 isotope has 20 neutrons
The most common isotope is 20
The atomic number of potassium is 19. So there are 19 protons and 19 electrons. The number of neutrons depends on the isotope. The most stable isotope of potassium (K-39) has 20 neutrons (39 - 19 = 20).
The most common isotope of carbon is carbon-12.The most common isotope of carbon is carbon-12.The most common isotope of carbon is carbon-12.The most common isotope of carbon is carbon-12.
Argon-40 is the most common isotope of argon, making up about 99.6% of natural argon. It is formed by the radioactive decay of potassium-40 in rocks.
40 Ar, because of its weight its very close to 40g/mol
39
The most common isotope is 20
Potassium 31 is potassium's normal state, the way you would find it on the Periodic Table. I presume potassium 41 is an isotope of potassium. (An isotope is the same atom, but it has a different number of neutrons, so the mass differs.)
Potassium has 20 neutrons in its most abundant isotope, potassium-39.
99.988% of potassium found in nature is not radioactive. 0.012% of natural potassium is 40K, which is radioactive and has a half life of about 1,248,000,000 years. Like all other elements, synthetic radioactive isotopes of potassium exist.
The most common isotope of silicon is the isotope 28Si: 92,23 %.
Na -23 is the most abundant isotope, because the atomic massfor Na on the periodical table of elements is 22.99 and 22.99 isclosest to 23.
The nucleus of potassium is the central core of the potassium atom consisting of protons and neutrons. It has 19 protons, making it the atomic number of potassium, and the number of neutrons can vary depending on the isotope of potassium.
The atomic number of potassium is 19. So there are 19 protons and 19 electrons. The number of neutrons depends on the isotope. The most stable isotope of potassium (K-39) has 20 neutrons (39 - 19 = 20).
Vanadium-51 is the most common isotope.
