Radioactive Decay Curve Explained - Half-Life Visualization #128382 (License: Personal Use)

The graph plots the number of atoms of a specific radioactive isotope versus time in seconds, starting from 100 atoms at t=0. Red markers and annotations highlight each 10-second interval where the quantity halves (100 → 50 → 25 → 12.5), visually reinforcing the exponential nature of radioactive decay. The smooth curve follows the equation N(t) = N₀·e^(-λt), where λ corresponds to a half-life of 10 seconds.

Used in educational web pages, textbooks, or science blogs explaining nuclear physics concepts like half-life and exponential decay; targets students, teachers, and curious learners seeking intuitive understanding of radioactivity.
