Question

The trends in atomic and ionic radii as we move from Li to Cs

Answer 1

Answer:

The atomic and ionic radii increases as we move from Li to Cs. ( Down the group) .

Explanation:

as we move down the group the no. of shell increases as atomic no. increases, atomic radii also increases but all the elements in the group have equal no. of valence electrons so the electrostatic force of attraction from nucleus to outermost electrons is same.
