Question
Give the trends in atomic size on moving down the group.
Advertisements
Solution 1
The atomic size of an atom increases when we go down a group from top to bottom.
Solution 2
Moving down a group causes an increase in atomic size, which also changes with period. An additional shell is added, increasing the atom's size.
