Identify all true statements from the following. O The nucleus of an atom contains only neutrons. O The number of nucleons present in the nucleus is equal to the number of electrons present outside the nucleus of the atom. OThe nucleus accounts for almost all the mass of an atom. The nucleus of an atom is positively charged. O The nucleus accounts for almost all the volume of an atom. OThe nucleus can be positively or negatively charged depending on the identity of the atom. The nucleus of an atom is neutral. O The number of protons present inside the nucleus is equal to the number of electrons outside the nucleus of an atom.
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.
