Answer with truc or false of the following: . The mumber of protons in a nucleus is called the ntomic number z. 2. Alpha particle is a Hydrogen nucleus, A Beth rays. these rays consists of electrons, they have more penetraling-power-than-alpha particles . Gamma rays: these rays consist of neutrons-particles. s IWhen a nucleus undergoes gamma decay, a new element is formed. 6- When a nucleus emits a photon, its atomic number decreases. 1. In nuclcar reaction there are a conscrvation of mass, energy, momentum and charge. he nutlear force becomes weak-if-the nucleus contoins loo many neurons compared to the number of protons: 9- The chemical behavior of an atom depends upon the electrons orbiting around its nucleus. 10-The half-life of a radioactive substance does not-depends upon the mass of the-substancec-
Radioactive decay
The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. This periodic table's elements come in a variety of shapes and sizes. Several of these kinds are stable like nitrogen-14, hydrogen-2, and potassium-40, whereas others are not like uranium-238. In nature, one of the most stable phases of an element is usually the most prevalent. Every element, meanwhile, has an unstable state. Unstable variants are radioactive and release ionizing radiation. Certain elements, including uranium, have no stable forms and are constantly radioactive. Radionuclides are elements that release ionizing radiation.
Artificial Radioactivity
The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
