Question

Arrange the following elements in order of decreasing nonmetallic character: $Ge,Sn,Pb,Si$

• A. $Pb,Sn,Ge,Si$
• B. $Ge,Sn,Pb,Si$
• C. $Si,Ge,Sn,Pb$
• D. They all have equal nonmetallic character since they are all in the same column of the periodic table
• E. None of the above

Answer 1

The correct option is C $Si,Ge,Sn,Pb$

As we know that down the group metallic character increases because the reducing nature i.e ability to loose electron increases.

So, the order is

$Si<Ge<Sn<Pb$

Ans :- C
