1.	If an isotope of hydrogen has two neutrons in its atom, its atomic number and mass number will respectively beA. 2and 1B. 1 and 1C. 3 and 1D. 1 and 3
Answer» Correct Answer - D The atomic number of isotope of hydrogen is alasy opne so it have only one protonn in its nuclesus and given that it have two neutrons.It menas that its mass number is 3.
