Two samples of carbon tetrachloride were decomposed into

Solution 31E First let’s see what is an isotope , before we write the symbol with superscript and subscript. Isotopes are atoms with the same number of protons but have different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, we can also say that isotopes are elements with the same atomic number but ifferent mass number. Now we write the chemical symbol of each isotope with subscripts and superscripts: The representation for chemical symbol of an atom is as shown below : Where, ‘X ’ is symbol of element, ‘ is the mass number, and ‘Z’ is the atomic number. (a) the isotope of platinum that contains 118 neutrons : Platinum is a chemical element having symbol P t. Given, Number of neutrons = 118. We need to find
