Question

will the element f(z=9) and Cl ( z=17) show similar properties ? why?​

Answer 1

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. ... \maltese✠ Same group elements have similar properties because they have same valence electrons.

Answer 2

Yes, F(z=9) and Cl(z=17) will show similar properties.

The electronic configuration of F will be (2,7) and that of Cl will be (2,8,7).

As both have the same number of valence electrons, they will exhibit similar properties, both gain an electron to form a monovalent anion and hence are extremely oxidizing in nature.

As both have the same number of valence electrons, both lie in the same group (Group VII A) of the periodic table and are halogens.
