Answer
(a) Isotopes — Carbon has two isotopes i.e., 6C12 and 6C14. They have same electronic configuration as they have same atomic numbers = 6. Hence, their electronic configuration is 2, 4.
(b) Isobars — Calcium [20Ca40] atomic number 20 and argon [18Ar40] atomic number 18 are isobars as both have same mass number i.e., 40 and different atomic numbers.
Electronic configuration of 20Ca40 is 2, 8, 8, 2.
Electronic configuration of 18Ar40 is 2, 8, 8.
