Radon
Radon gas is produced from the natural decay of uranium in soil, rocks, and water. When uranium breaks down, it forms radium, which then decays to produce radon gas. Radon can seep into buildings through cracks in the foundation or gaps in walls and floors.
Radium is a solid, radon is a gas. Both are radioactive.

BACTERIA
To avoid the oxydation of radium (as a metal).
It breaks down biological waste and turns it inot methane gas with the help of bacteria.
When citric acid breaks down, it releases carbon dioxide gas, water, and energy.
The boiling pint of radium is 1 737 0C.
When calcium carbonate (limestone, CaCO3) breaks down, carbon dioxide (CO2, gas) and calcium oxide (CO, solid) are formed
Most oceanic gas hydrates are created when microbial activity breaks down organic matter trapped in ocean-floor sediments. These microbes decompose the organic material, producing methane as a byproduct. Under specific conditions of low temperature and high pressure, this methane can then combine with water to form gas hydrates. This process is crucial for the formation of gas hydrates in marine environments.

When hydrogen peroxide decomposes, it breaks down into water and oxygen gas.
