The possible isotope of element E which has a mass number that is 2.50 times its atomic number and where the atomic number is equal to the mass number of another isotope Y which in turn has an atomic number equal to the neutron number of Se-82 needs to be identified. Concept introduction: 1. Atoms are composed of fundamental subatomic particles: electrons, protons and neutrons and in general can be described by two quantities: Atomic number (Z) and Mass number (A). 2. For neutral atoms: Number of protons = Number of electrons = atomic number Z ----- (1). Number of neutrons = Mass number (A) − Atomic number (A) ----- (2). 3. Ions are charged species that are formed by the loss (positive ion, cation) or gain (negative ion, anion) of electrons.
