Question

How are potassium-39, potassium-40, and potassium-41 different from each other? Write the isotope symbol for each?

Answer 1

These are different isotopes of potassium nuclei

 

The symbols are

 

₁₉K³⁹ , ₁₉K⁴⁰ and ₁₉ K ⁴¹

  Each isotope has same number of proton in all the three nuclei ie 19 

but number of neutrons  are  20, 21 and 22 respectively and so they have different nuclear properties but similar chemical properties
