    The average distance and the most probable distance of an electron from the nucleus in the 1s orbital of a hydrogen atom are equal to 1.5a0​ and a0​ (Most probable distance is the distance where electron is highest probable so it is the radius of that orbit a0​). The value of 1.5a0​ is 0.529A˚. Hence, the average distance and the most probable distance of an electron from the nucleus in the 1s orbital of a hydrogen atom are equal to 0.794A˚ and 0.529A˚ respectively. so option 1/2
