Answer to Question #77925 in Inorganic Chemistry for Galaxy

Question

Among the Group 4 elements moving from carbon to silicon the covalent radius increases sharply afterwards the increase is gradual, this is attributed to __________.

Answer 1

As we move down the group upto silicon, the effect of additional shell leads to a sharp increase in size, subsequently it becomes easy for electron loss, leading to gradual increase in size.

As we move down the group after silicon, reduction takes effect as against oxidation leading to gradual increase in size.
