Question

9. 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 decrease from Li to F.
(b) Identify the most
(i) metallic and
(ii)non-metallic element.​

Answer 1

(ii) non-metallic element

Answer 2

a)due to increase in number of electrons hence leading to more nuclear charge

b)most metallic -li

nom metallic -f

hope it helps

plz mark brainliest

Answer 3

Becoz no. Of subshell remain same but nuclear charge increses continously..so attraction between positive charged nucleus and negative charge electron increses..so radii decreses
