Describe the general trends in the following properties of the elements in Groups 13 and 14.

Oxidation states

Long Answer

Solution

Possible oxidation states Group 13 elements are from +3 to –5. But the stability of +1 oxidation state increases down the group due to inert their effect than the stability of +3 oxidation state. 

Similarly, in group 14, The common oxidation states shown by the carbon family are +2 and +4. Due to the inert pair effect, stability of +2 oxidation state increases then the stability of +4.
