Define oxidation state. How does it vary in the groups ?

Define electronegativity. How does it vary in the periodic table?

The oxidation state of nitrogen varies from:

Why does the stability of + 3 oxidation state decrease on moving down the group 13 ?

The oxidation state of phosphorus vary from

How does the stability of +1 and +3 oxidation states vary in group 13?

What do you understand by catenation ? How does the property vary in group 14?

Aluminium exhibits +3 oxidation state. As we move down the group, +1 oxidation state gets more stable. This is a consequence of

The heavier members of 13 and 14 groups besides the group oxidation state also show another oxidation state. Down the group (darr) , the stability of higher oxidation state increases. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups. Heavier members of group 13 exhibit oxidation state.

Which of the following acts as the strongest acid ?
