Question

How does the basic nature of oxides of the elements vary down a group and across a period?

Answer 1

• Basic nature of oxides- A basic oxide is an oxide which when combined with water gives off a base.
• Basic nature of oxides directly proportional to metallic character of an element.
• As, metallic character increases down a group and decreases across a period therefore, basic nature increases down a group and decreases across a period.
