…of naturally occurring but radioactive potassium-40 is measured to be 39.964008 amu.
What is 40k element?
Cite. Please visit the Potassium element page for information specific to the chemical element of the periodic table.
Why is the mass number of potassium-39?
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. Hence, number of neutrons is 39 – 19 which is 20. Potassium-40 – It has 19 protons and atomic mass is 40.
How many neutrons are in potassium-40?
Potassium-40 has twenty one neutrons.
What is the neutrons of potassium?
The element of potassium has the symbol K. The nucleus of an atom of potassium contains 19 protons and 20 neutrons.
How do we find atomic mass?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons.
