Question

Will the element F (Z=9) and Cl (Z=17) show similar properties. Why?for one mark​

Answer 1

Required Answer :-

Given elements are Flourine (Z=9) and Chlorine (Z=17). Yes , Flourine and chlorine have similar properties.Both Flourine and Chlorine atoms have same valence electrons i.e , 7 valence electrons. They also belong to same group in periodic table. Chlorine and Flourine have same valency. Moreover , The elements belonging to same group posses similar properties. Hence , We can say that Flourine (Z=9) and Chlorine (Z= 17) show similar properties.

Why elements of same

group have similar

properties ?

$\maltese$ Same group elements have similar properties because they have same valence electrons.Valence electrons determine most of the properties of elements.
