Identify the element represented by each of the following symbols and give the number of protons and neutrons in each: (a) , (b) , (c) , (d) .
Solution : Step 1: Here, we have to find the element name with the help of mass number and atomic number given. In the symbol of an element (neutral atom) the mass number is shown in the super script and atomic number is shown in subscript. Atomic number gives the number of protons and electrons in an atom as in an atom, number of protons is equal to number of electrons. Mass number is sum of the number protons and number of neutrons .
