What is radioactivity in chemistry simple words?

Radioactivity is the spontaneous emission of radiation in the form of particles or high energy photons resulting from a nuclear reaction. A substance that contains unstable atomic nuclei is considered to be radioactive. Radioactive decay is a random or stochastic process that occurs at the level of individual atoms.

What radioactive means?

1 : the giving off of rays of energy or particles by the breaking apart of atoms of certain elements (as uranium) 2 : the rays or particles that are given off when atoms break apart. radioactivity. noun.

What is radioactive element in chemistry?

Radioactive elements are made up of atoms whose nuclei are unstable and give off atomic radiation as part of a process of attaining stability. The emission of radiation transforms radioactive atoms into another chemical element, which may be stable or may be radioactive such that it undergoes further decay.

What is the science in radioactivity?

Radioactivity is the release of energy from the decay of the nuclei of certain kinds of atoms and isotopes. Radioactive nuclei are nuclei that are unstable and that decay by emitting energetic particles such as photons, electrons, neutrinos, protons, neutrons, or alphas (two protons and two neutrons bound together).

What is radioactivity caused by?

What causes atoms to be radioactive? Atoms found in nature are either stable or unstable. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.

Why is a radioactive?

What causes atoms to be radioactive? An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.

What is radioactivity and its types?

Radioactivity refers to the particles which are emitted from nuclei as a result of nuclear instability. The most common types of radiation are called alpha, beta, and gamma radiation, but there are several other varieties of radioactive decay.

What is radioactivity made of?

Radiation refers to the particles or energy released during radioactive decay. The radiation emitted may be in the form of particles, such as neutrons, alpha particles, and beta particles, or waves of pure energy, such as gamma and X-rays.

What is the other name of radioactivity?

Where does radioactivity occur?

nucleus
In radioactive processes, particles or electromagnetic radiation are emitted from the nucleus. The most common forms of radiation emitted have been traditionally classified as alpha (a), beta (b), and gamma (g) radiation.

What are some examples of radioactivity?

Radiation Examples. Here are some examples of different types of radiation: ultraviolet light from the sun. heat from a stove burner. visible light from a candle. x-rays from an x-ray machine. alpha particles emitted from the radioactive decay of uranium. sound waves from your stereo.

What are the uses of radioactivity?

Radioactivity Uses

What are the different types of radioactivity?

There are three different types of radioactivity(alpha, beta and gama) which have the following characterstics: 1-Alpha particles are the nuclie of helium atom which are formed on the removal of all the electrons from helium atom and the remainser is the positive nucleus of heilum atom called alpha.

Is radioactivity a chemical property?

Radioactivity is the defined as emission of radiations from an unstable nucleus…. A chemical property is a property that is associated with chemical reactions and changes in the composition of matter. Examples of chemical properties are heat of combustion, flammability , toxicity, etc.
