Questions & Answers

Q: What is the equation for the decay constant in radioactive decay?

The equation for the decay constant is lambda = 2.303 / (log10(n0) - log10(n)), where lambda represents the rate of decay over time.

Q: How is the graphical representation of radioactivity decay achieved?

By using the equation y = -mx + c, where y is log N, x is time, and the slope represents the decay constant, we can graphically represent the decay of a radio element.

Q: What does the slope of the graph represent in radioactive decay?

The slope of the graph represents the decay constant of the radio element, indicating how quickly it decreases over time.

Q: Why does the activity of a radio element decrease over time?

The activity decreases as the radio element decays, leading to a decline in the amount of substance present due to radioactive decay.
