Unstable elements that give off radiation are called radioactive elements. These elements have unstable atomic nuclei that undergo radioactive decay, emitting particles and/or electromagnetic radiation. Some examples of radioactive elements include uranium, plutonium, and radium.
Now, let's move on to the second part of your question. Tiny vesicles that form when short chains of amino acids gather together are called micelles. When a group of amino acids, specifically those with hydrophobic (water-repellent) side chains, are placed in water, they tend to arrange themselves in a way that minimizes their exposure to water. This results in the formation of micelles, which are tiny spherical structures with the hydrophobic amino acids clustered in the core and the hydrophilic (water-attracting) parts facing outward. Micelles are often formed by surfactant molecules, such as fatty acids or detergents, and play an important role in various biological processes, including the digestion and absorption of dietary fats.
