## [Chemistry] Periodic Trends in Properties of Elements

## INTRODUCTION

Periodic trends are specific patterns in the properties of elements which keep on repeating after regular intervals in the periodic table.

Following are the periodic trends in some of the properties of elements;

## ATOMIC RADII

### WHAT IS ATOMIC RADIUS?

Atomic radius is half of the distance between the nuclei of the two bonded atoms.

### MATHEMATICALLY

Atomic radius = d/2

Where,

D is the distance between the nuclei of two bonded atoms
