Atomic radii of the elements of the second period are given below:Period II elements:BBeONLiCAtomic radius (Pm):88111667415277i. Arrange them in decreasing order of their atomic radii. ii. How does the atomic radius change as you go from left to right in a period? Why?

Answer»

(i) Li > Be > B > C > N > O 

(ii) Atomic radius decreases on moving from left to right in a period of the periodic table. It is because force of attraction for the outermost electrons towards nucleus increases because of increased nuclear charge.
