[Audio] Welcome everyone, today we are here to learn about understanding an important concept in chemistry: Atomic Radius Trend. We are going to learn about how the atomic radius changes as atoms become larger and the different trends that occur depending on the location of the atoms in the periodic table. So, without further delay, let's get started!. 

Scene 1

[Audio] The atomic radius is an important concept in understanding the structure of elements in the periodic table. Generally, the atomic radius decreases from left to right across a period as the attractive force between the electrons and the nucleus increases, while the atomic radius increases when moving down a group due to an increase in energy levels. Understanding the trend in atomic radius can help us to better comprehend the structure of elements in the periodic table.. 

Scene 2

ATOMIC RADIUS TREND ON THE PERIODIC TABLE, ATOMIC RADIUS GENERALLY DECREASES AS YOU MOVE FROM LEFT TO RIGHT ACROSS A PERIOD ,AND INCREASES AS YOU MOVE DOWN A GROUP

The atomic radius decrease as you move from left to right : ( high attraction force this decrease the  atomic radius because the electrons become more closer to each other and when it’s less attraction force this increase the  atomic radius because the electrons become farther away from each other , this is inversely proportional  ) . And the atomic radius increase as you move from up to down : ( less energy level this decrease the atomic radius and more the energy level this increase the atomic radius  ,  this is directly proportional )
