Application OF Electronegativity || Acidic and Basic Character of Oxides || Hydration Energy and its Application

In amalgams of metal,Oxidation state of Mercury is

A Feo is basic in character. R: Oxides of Transition metals are basic when metal is in lower oxidation state

Assertion: MnO is basic whereas Mn_2O_7 is acidic. Reason: Higher the oxidation state of a transition metal in its oxide, greater is the acidic character.

Explain giving justification the trends in the following properties of elements, on moving , from left to right in a period, in the Modern periodic Table. (a) Variation of valency. (b) Change of atomic radius . (c) Metallic to non-metallic character. (d) Electronegative character. (e) nature of oxides.

Metallic Character The ability of an atom to donate electrons and form positive ion (cation) is known as electropositivity or metallic character. Down the group, metallic character increases due to increase in atomic size and across the period, from left to right electropositivity decreases due to decrease in atomic size. Non-Metallic Character The ability of an atom to accept electrons to form a negative ion (anion) is called non-metallic character or electronegativity. The elements having high electro-negativity have a higher tendency to gain electrons and form anion. Down the group, electronegativity decreases due to increase in atomic size and across the period, from left to right electronegativity increases due to decrease in atomic size Which of the following correctly represents the decreasing order of metallic character of Alkali metals plotted in the graph?
