Question

Answer 1

Answer #1

In periodic table , m

from left to right in any period = metallic character decrease

From top.to bottom in any group = metallic character increase

Now , Group 1 has highest metallic character and G-17 has lowest .

G = group

Metallic order = Fr ( G-1) > Ba ( G-2 ) > In( G-13 ) > Sn ( G-14 ) > Se ( G- 16 )
