Question

Arrange the following elements as per instructions in the brackets:
i) Boron, Carbon, Beryllium, Lithium (decreasing order of atomic size)
ii) Bromine, Chlorine, Iodide, Fluorine (decreasing order of election affinity)
iii) Silicon, sulphur, aluminum, chlorine (increasing order of electronegativity)
iv) Cl, Al, Na, S. (increasing order of ionization potential)
v) Ar, He, Ne. (increasing order of election shells)

Answer 1

i) Lithium > Beryllium > Boron > Carbon
ii) Chlorine > Fluorine > Bromine > Iodine
iii) Aluminum < Silicon < sulphur < chlorine
iv) Na < Al < S < Cl
v) He < Ne < Ar
