Question

In the correct order of Increasing atomic radius starting with the smallest in,en,sr,te,rn

Answer 1

There is a typo error, there is no element like 'en', it must be Ne(Neon). According to periodic trends, the elements in order of increasing atomic radius from smallest to largest are Neon (Ne), Indium (In), Tellurium (Te), Strontium (Sr), and Radon (Rn). The order should be Ne < In < Te < Sr < Rn.

Step-by-step explanation:

The order of increasing atomic radius starting with the smallest for the elements In (indium), En (presumably a typo and should be 'Ne' for neon), Sr (strontium), Te (tellurium), Rn (radon) should be considered according to the two main trends on the periodic table:

1. Atomic radii decrease from left to right across a row.
2. Atomic radii increase from top to bottom down a column.

Considering these trends: Ne would have the smallest atomic radius as it is farthest to the right and highest in the periodic table.

Following that logic, the order should be Ne < In < Te < Sr < Rn, with Rn having the largest atomic radius as it is the farthest to the left and lowest in the periodic table.
