Answer:
<h2> radionuclide is an atom that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferred to one of its electrons to release it as a conversion electron; or used to create and emit a new particle from the nucleus</h2>
sand and ammonium chloride are insoluble in water but sodium chloride is soluble in water .ammonium chloride sublimates. so you first heat the mixture in a beaker covered with a watch glass then the ammonium chloride will accumulate on the watch glass leaving a mixture of sodium chloride and sand you then dissolve the mixture then filter using a beaker and a filter paper the filtrate is salt solution while the residue is sand you then evaporate the salt solution to remain with salt
The nucleus, that dense central core of the atom, contains both protons and neutrons. Electrons are outside the nucleus in energy levels. Protons have a positive charge,neutrons have no charge, and electrons have a negative charge. A neutral atom contains equal numbers of protons and electrons.
