Alpha nuclide

Alpha nuclide is a kind of atom that has a special type of particle inside it called an alpha particle. An alpha particle is made up of two protons and two neutrons, and it's very big and heavy compared to other particles.

When alpha particles are inside an atom, they can make the atom unstable and cause it to break apart. This breaking apart process is called radioactive decay.

Some elements, like uranium and plutonium, are alpha nuclides because they naturally have alpha particles inside them. When these elements decay, they give off alpha particles, which can be dangerous if they're breathed in or ingested.

Scientists can use alpha nuclides in a variety of ways, such as for medical research, nuclear power, or creating new materials. However, it's important to handle alpha nuclides safely to avoid harm to people or the environment.
