2) An element with atomic number of 82 has four naturally occurring isotopes. The first isotope has 122 neutrons, the second has 124 neutrons, the third has 125 neutrons, and the fourth has 126 neutrons. Identify the element and write the atomic symbol for the four isotopes below. [HINT: Atomic symbol for isotope with 1 proton and 1 neutron is: \( { }_{1}^{2} H \) ] Element: Isotope symbol 1: Isotope symbol 2: Isotope symbol 3: Isotope symbol 4:
