Question

THE ATOMIC RADII OF FIRST GROUP ELEMENTS ARE GIVEN BELOW: GROUP 1 ELEMENT 1) NA 2) K 3) RB 4) CS ATOMIC RADII 1) 86 2) 231 3) 244 4) 282.SATE BEHIND THE OBSEREVED TREND IN ABOVE ELEMENTS. PLEASE............ANSWER THIS PLEASE ​

Answer 1

Answer:

Smallest Atomic Radii ---Lithium

Largest Atomic radii -- Cesium

Explanation:

As we move down in a group, atomic radius increases.

Answer 2

Answer:

hey mate here is ur ans...

Explanation:

from the observation as we go down the table , the atomic radi of the elements increase due to increase in the no.of electrons..

as the no.of electrons increase the no.of shell increase so the atomic radi also increase because the atomic radii is the distance from centre of atom to the valence electron....

so the atomic radii increase...

hope it will be helpful... please mark as brainlist answer....
