What is the number of electrons in potassium 40?
This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons. To find out the number of neutrons you have to look at the atomic mass or weight of the element. This can also be found in the periodic table.
How many neutrons are in the potassium?
20 neutrons
potassium with 20 neutrons 3919K.

What is the abundance of potassium-40?
about 0.01\%
Potassium-40 has a relative abundance of about 0.01\% naturally, and exists within the potassium in the body tissues. Carbon-14 may also exist within the body tissues due to the natural turnover of carbon by the body, even though its half-life is relatively short.
What is the Amu of potassium-40?
39.964008 amu
binding energy measurement and beta decay …of naturally occurring but radioactive potassium-40 is measured to be 39.964008 amu. Potassium-40 decays predominantly by β-emission to calcium-40, having a measured mass 39.962589.
How many neutrons does 41 19 Potassium have?
Potassium-40 – It has 19 protons and atomic mass is 40. Hence, number of neutrons is 40 – 19 which is 21. Potassium-41 – It has 19 protons and atomic mass is 41. Hence, number of neutrons is 41 – 19 which is 22.
How many neutrons do potassium 39 and potassium 41 have?
Since K is atomic number 19, it has 19 protons. It would need 20 neutrons to get to K 39. So K 41 has 19 protons and 22 protons. The difference between each of those isotopes is 2 neutrons.
Does potassium-40 or Argon 40 have more neutrons?
Which atom has more neutrons, potassium-40 or argon-40? Argon-40 has 22 neutrons (40 − 18 = 22), and potassium-40 has 21 neutrons (40 − 19 = 21).
Does potassium-40 have more neutrons than calcium 40?
Potassium 40 contains odd numbers of both – 19 protons and 21 neutrons. In both argon 40 and calcium 40, however, the number of protons and neutrons are even, granting them that extra stability.
How many neutrons does potassium 39 K potassium-40 have?
twenty neutrons
2: How many neutrons do (K) potassium-39 and potassium-40 have, respectively? Potassium-39 has twenty neutrons. Potassium-40 has twenty one neutrons.
What is the percentage of potassium-40?
0.0117\%
Potassium-40 (40K) is a naturally occurring radioactive isotope of the common element potassium (potassium represents about 2.4\% by weight of the earth’s crust). The half-life of 40K is 1.248 x 109 years [1] its origins are primordial. 40K has an atomic percent abundance of 0.0117\%.
