In chemistry, the number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element to which the atom belongs. For example, the atomic number of chlorine is 17; this means that each chlorine atom has 17 protons and that all atoms with 17 protons are chlorine atoms. The chemical properties of each atom are determined by the number o… self service dog wash ukWebbAtomic number, atomic mass, and relative atomic mass Atoms of each element contain a characteristic number of protons.
