Q. what is alpha particle
Q. what is gamma radiation
Q. what is beta particles
Answers
Answer:
Q. Alpha Particle -: a very small piece of matter with a positive electric charge passing through it, that is produced in a nuclear reaction.
Q. Gamma Radiation-: A gamma ray, also known as gamma radiation, is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy.
Q. Beta Particle-: a fast-moving electron that is given off when an atom breaks up.
hope it will help you dear
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways. Alpha particles are named after the first letter in the Greek alphabet, α. The symbol for the alpha particle is α or α2+. Because they are identical to helium nuclei, they are also sometimes written as He2+
or 4
2He2+
indicating a helium ion with a +2 charge (missing its two electrons). Once the ion gains electrons from its environment, the alpha particle becomes a normal (electrically neutral) helium atom 4
2He.
