Question

what are trends in atomic radii/ size in periodic table ?? 5 mark question ​

Answer 1

Answer:

◆Along the period ( left to right )

the Atomic radii is ∝ 1 / Necular charge

Necular charge increase along the period

therefore , Atomic radii decrease along the period

● Dowm the Group (top to bottom)

Atomic radii ∝ no. of shell

no of shell increase Dowm the Group

therefore , Atomic Radii increase Dowm the Group
