Question

Periodic trends of group 13 elements atomic radius

Answer 1

The atomic radii of group 13 elements are smaller than that of corresponding s block elements.

The atomic radii increases down the group

with exception of Ga whose radius is slightly lesser than Aluminum the Ga experiences greater force of attraction towards the nucleus to result in lower size of Ga than Al

Boron has the smallest atomic radii while Thallium has the largest

Answer 2

Answer:

atomic radii atomic and ionic radii of group 13 elements increases from top to bottom in the group this is due to increase in the number of energy shells in its exceeding element however the atomic radius of gallium is less than that of aluminium
