Each element has a unique number of protons. So atomic number help in the identification of elements. What is Mass Number? An atom consists of protons, neutrons, and electrons. Since the mass of electrons is negligible as compared to protons and neutrons, the mass of an atom is determined ...
18 (a)The relative atomic masses of elements can be determined using a mass spectrometer.(i) Define the term relative atomic mass.(3)(ii) Describe fully how positive ions are formed from gaseous atoms in a mass spectrometer.(ii) The following dat a were obtained from the mass spectrum of...
The atomic mass of an element is the sum of the masses of all protons and neutrons in the nucleus in atomic mass units. An element exists in several isotopic forms in which two or more atoms have the same atomic number but different mass numbers or atomic masses....
