REDIUS TREND. DONE BY ROWAIDA MAGDY 10A. 

Scene 1

ATOMIC REDIUS 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. 

Scene 2

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