How It Works

Step 1: Access the Radioactive Decay Calculator
Open the nuclear chemistry calculator.

Step 2: Input Initial Amount, Decay Constant, and Elapsed Time
Enter the starting mass/moles, the constant ($\lambda$), and the time passed.

Step 3: Click the Calculate Button
Press 'Calculate Remaining Amount'.

Step 4: Review the Amount Remaining
The tool will display the mass or number of nuclei still present after the decay period.
