Normal levels range between 3.5-5.2 so you have nothing to worry about at this point.
K-39 is the most abundant, constituting about 93 % of the atoms in naturally occurring potassium.
Potassium-39 and potassium-41 are isotopes of potassium, meaning they have the same number of protons but different numbers of neutrons. Potassium-39 has 20 neutrons, while potassium-41 has 22 neutrons. This difference in neutron number results in different atomic masses for the two isotopes.
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.
Potassium-39 has 20 neutrons. This is because the atomic number of potassium is 19, which represents the number of protons in its nucleus. Subtracting the atomic number from the atomic mass gives you the number of neutrons.
The atomic number is 19 and the mass number of its most abundant isotope K-39 is 39 (19 protons + 20 neutrons) while the mass of that isotope is 38.96371 a.m.u.The relative atomic mass of the element potassium, K, is 39.10 g/mole.
Every atom of potassium has a mass of 39 amu. Each mole of potassium has a mass of 39 grams.
The numbers 39, 40, and 41 after the element name potassium refer to the mass number of the isotopes of potassium. Potassium has three isotopes: potassium-39, potassium-40, and potassium-41, which have 19, 20, and 21 neutrons respectively.
A potassium-39 atom has 19 protons since the atomic number of potassium is 19.
Potassium has three naturally occurring isotopes: potassium-39, potassium-40, and potassium-41. The most common isotope is potassium-39, which makes up about 93% of naturally occurring potassium.
Potassium has 20 neutrons in its most abundant isotope, potassium-39.
The atomic number of potassium is 19.The atomic weight of potassium is 39,0983(1).The mass number of the isotope potassium-39 is 39.
The atomic mass of potassium is 39 ,therefore the number of mole is 39 /39,which is 1then multiple by Avogadro number you get 6.022*10^24
The standard atomic notation for potassium is K-39. This indicates that the element has a mass number of 39.
39 is the atomic mass of one atom of potassium. This is essentially the weight of one atom
K-39 is the most abundant, constituting about 93 % of the atoms in naturally occurring potassium.
The appropriate symbol for an isotope of potassium-39 corresponding to the isotope notation A Z X is ^39_K19.
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.)
