The correct statement is:
**After a half-life, half of the undecayed nuclei of a radioactive element decays.**
This means that after one half-life has passed, half of the original amount of radioactive nuclei has transformed into its decay products, while the other half remains undecayed. The decay constant does not change, and it does not halve or double after a half-life.
**After a half-life, half of the undecayed nuclei of a radioactive element decays.**
This means that after one half-life has passed, half of the original amount of radioactive nuclei has transformed into its decay products, while the other half remains undecayed. The decay constant does not change, and it does not halve or double after a half-life.
