Solution
Argon and Calcium are isobars because they have the same mass number which is 40 and both have different atomic number Argon = 18 and Calcium = 20.
Protium and Deuterium are isotopes because they have a same atomic number which is 1 but have a different mass number. Isotopes have same chemical properties because all the isotopes have the same electrons in their outermost shell and their electronic configuration are same.
