Question

fill in the missing words
use the periodic table to answer this question. three isotopes of potassium are stable: potassium-39, potassium-40 and potassium-41. only one isotope of potassium is the most abundant. the most abundant isotope is blank

Explanation:

To determine the most abundant isotope of potassium, we refer to the atomic mass of potassium on the periodic table. The atomic mass of potassium is approximately 39.10 amu. The atomic mass is a weighted average of the masses of the isotopes, with the most abundant isotope having a mass closest to the atomic mass. Among potassium - 39, potassium - 40, and potassium - 41, 39 is closest to 39.10. So the most abundant isotope is potassium - 39.

Answer:

potassium - 39
