Final answer:The element symbol of theisotopewith 45neutronsand 36 electrons is 81Tl, which represents thallium. The mass number of this isotope is 126, and the number of protons is 81.Explanation:Anatomis neutral when it contains equal numbers of electrons and protons. The atomic number (Z) of an element is equal to the number ofprotonsit contains. The mass number (A) of an atom is the sum of its protons and neutrons. In this case, the isotope has 45 neutrons and 36 electrons. Since the number of protons is equal to the number of electrons, theelement symbolof this isotope is 81Tl, which stands forthallium. The mass number is found by adding the number of protons and neutrons: 81 + 45 = 126. Therefore, the mass number of this isotope is 126, and the number of protons is also 81.Learn more aboutisotopehere:brainly.com/question/31505270#SPJ11...
