Question
Statement 1: The mass of a nucleus can be either less than or more than the sum of the masses of nucleons present in it
Statement 2: The whole mass of the atom is considered in the nucleus
- Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
- Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
- Statement 1 is True, Statement 2 is False
- Statement 1 is False, Statement 2 is True
The correct answer is: Statement 1 is False, Statement 2 is True
The whole mass of the atom is concentrated at nucleus and 
(Sum of the masses of nucleons) because, when nucleons combine some energy is wasted
