Decay and Atoms: Calculating Mo-99 Requirements at Equilibrium - 1x10^9 Atoms"

In summary, decay is the natural process in which an unstable atom loses energy and transforms into a more stable form. It occurs when the nucleus of an atom becomes unstable and releases energy in the form of radiation to achieve a more stable state. The three main types of decay are alpha, beta, and gamma decay, and the rate of decay is measured using the half-life. Decay cannot be controlled or stopped, but external factors can influence its rate.

Yes, this belongs in one of the "Homework and Coursework Questions" sub-forums, probably "Advanced Physics." Please re-post there, and show some work or at least thoughts about it.
 

1. What is decay?

Decay is the natural process in which an unstable atom loses energy and transforms into a more stable form.

2. How does decay occur?

Decay occurs when the nucleus of an atom becomes unstable due to an imbalance of neutrons and protons. The nucleus then releases energy in the form of radiation to achieve a more stable state.

3. What are the types of decay?

The three main types of decay are alpha decay, beta decay, and gamma decay. In alpha decay, the nucleus emits an alpha particle (two protons and two neutrons). In beta decay, the nucleus emits a beta particle (an electron or positron). In gamma decay, the nucleus releases energy in the form of high-energy photons.

4. How is the rate of decay measured?

The rate of decay is measured using the half-life, which is the amount of time it takes for half of the unstable atoms in a sample to decay into a more stable form. The half-life is a constant for each type of decay and can vary from milliseconds to billions of years.

5. Can decay be controlled or stopped?

No, decay is a natural process that cannot be controlled or stopped. However, the rate of decay can be influenced by external factors such as temperature, pressure, and radiation.
