the elements of the second period of the periodic table are given below Li,Be,B,C,N,O,F (a) give reason to explain why atomic radii decreases from Li to F
Satya9937:
From Li to F nuclear force increases. so nucleus attract electron cloud more towards the center. so increase in nuclear power radius decreases

Due to atomic radius
ek aur he identify the most (a) metallic (b) non metallic element

The atomic radius decreases because along the period the nuclear charge effect on the atoms increases, due to the increase in nuclear charge effect the electrons that revolve around the nucleus are pulled closer towards the nucleus. Due to this the radius of the atom decreases.
