The element krypton (symbol: Kr) has several radioactive isotopes. Here
listed are several of these Isotopes along with their half lives: Kr-73, 27s;
Kr-74, 11.5 min; Kr-76, 14.8 h; Kr-81, 210,000 y. Which of the isotopes is
most stable and which of the isotopes is most radioactive? Explain your
answer.

Respuesta :

Answer:

Kr-81 is most stable because of its high half lige and kr-73 is the most radioactive because of its least half life

Explanation:

Stability is directly proportional to half life of a reaction
