Class 12 Physics simulations · Nuclei

Radioactive decay

See individual nuclei disappear while the population follows a half-life curve.

Open the simulation

What to notice

After each half-life, approximately half of the undecayed population remains.

Key relation

N(t) = N₀(½)^(t/T½)

Try this

Double the half-life. Compare the steepness of the decay curve.

What you can change

• Initial nuclei: 48 to 120
• Half-life: 3 to 12 s
