The number of protons, neutrons and electrons of two elements are given. Using these numbers, the symbols of elements are to be determined. Concept introduction: In a neutral atom, the number of protons and electrons are same and equal to the atomic number of that atom but in an ion, they are different in number depending on the charge on the ion. The sum of the number of protons and number of neutrons is equal to the mass number of that atom or ion. To determine: The symbol of ions having the given number of protons, neutrons and electrons.
