What element is the most radioactive lithium sodium or potassium?
Potassium is the most radioactive among lithium, sodium, and potassium. Potassium has a naturally occurring radioactive isotope, potassium-40, which is present in all potassium samples and contributes to its radioactivity.
Explain how you would calculate the number of neutrons in potassium -40?
To calculate the number of neutrons in an atom of potassium-40, subtract the atomic number (which is 19 for potassium) from the mass number (which is 40 for potassium-40). So, 40 (mass number) - 19 (atomic number) = 21 neutrons in potassium-40.
How do you prepare 40 percent of potassium sodium tartrate?
To prepare a 40% solution of potassium sodium tartrate, you would need to weigh out the appropriate amount of the salt and dissolve it in a specific volume of water to get the desired concentration. For example, to prepare 100mL of a 40% solution, you would mix 40g of potassium sodium tartrate with enough water to bring the final volume to 100mL.
What does the numbers 39 40 and 41 after the element name potassium refer to?
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.
How many neutrons do (K) potassium and potassium -40 have?
Potassium (K) typically has 19 neutrons in its nucleus. Potassium-40 is a radioactive isotope with 21 neutrons in its nucleus.
Which potassium salt k is the most soluble at 40c and at 80 c?
Potassium nitrate (KNO3) is the most soluble potassium salt at both 40°C and 80°C due to its high solubility in water. Potassium chloride (KCl) and potassium sulfate (K2SO4) are less soluble at these temperatures compared to potassium nitrate.
Which potassium salt is the least soluble at 40 C and at 80 C KBr or KCl?
At 40°C, KBr is less soluble than KCl. At 80°C, the trend may reverse, with KCl possibly being less soluble than KBr. The solubility of salts typically increases with temperature, so KBr may be the least soluble at both 40°C and 80°C.
What are the three naturally occurring isotopes of potassium?
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.
Who is madee?
Most argon is made by radioactive decay of potassium-40.
What is the most common isotope for potassium?
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.
What is emitted when potassium -40 decays?
Potassium-40 decays by emitting a beta particle, which is an electron. This decay process transforms potassium-40 into calcium-40.
Which is more abundant K39 K40 OR K41?
K-39 is the most abundant, constituting about 93 % of the atoms in naturally occurring potassium.
Explain how you would calculate the number of neutrons in potassium -40?
To calculate the number of neutrons in an atom of potassium-40, subtract the atomic number (which is 19 for potassium) from the mass number (which is 40 for potassium-40). So, 40 (mass number) - 19 (atomic number) = 21 neutrons in potassium-40.
Who is argon made?
Most argon is made by radioactive decay of potassium-40.
Who made argon?
Most argon is made by radioactive decay of potassium-40.
What element is the most radioactive lithium sodium or potassium?
Potassium is the most radioactive among lithium, sodium, and potassium. Potassium has a naturally occurring radioactive isotope, potassium-40, which is present in all potassium samples and contributes to its radioactivity.
How you calculate the number of neutrons in potassium-40?
By subtracting 19 (atomic number of Potassium) from 40. You should come out with 21, which is the number of neutrons in potassium-40
