Expert Answer
From this chapter questions like naming the element with atomic number greater than 100 and their symbol can be asked. Various reasons explaining trends in variations of atomic size,ionisation enthalpy, electron gain enthalpy can be asked. If the trend observing various properties of elements shows any anamolous then questions based on it can be asked.Even questions based on anamolies observed by certain elements of periodic table and reasons related to it can be asked
