Why acidic character of oxides of group 15 elements decreases down the group?

The ability of the hydride to donate a hydrogen ion can be directly correlated with the decreasing bond strength of the element-hydrogen bond. That is, as the bond strength decreases down the family, the acidity increases. For the same reason, the general chemical reactivity of nonmetal hydrides also increases with increasing atomic number of the nonmetal.

Is oxide basic?
The oxide ion itself is basic, but oxides of various elements may be acidic, basic, or amphoteric.
Are all oxides acidic?
No. A number of metal oxides are basic.
Are metals oxides acidic?
No, metal oxides are basic in nature.
Is carbon dioxide an acidic gas?
Yes it is. All the oxides of non-metals are acidic and oxides of metals are basic
Is sulfur dioxide gas basic or acidic in nature?
sulphur dioxide is an acidic gas. Remember;- Groups 1 & 2 oxides are basic. None metal oxides are acidic.
What is the nature of oxides of s-block elements acidic or basic or amphoteric or neutral?
acidic because when alkali oxides are reacted with water they give a acid
Is oxide basic?
The oxide ion itself is basic, but oxides of various elements may be acidic, basic, or amphoteric.
How can the classification of oxides be related to their metallic and non-metallic character?
The classification of oxides is related to their metallic and non-metallic character based on the type of elements they are composed of. Metallic oxides are formed by the combination of a metal with oxygen and are generally basic in nature. Non-metallic oxides, on the other hand, are formed by the combination of a non-metal with oxygen and are generally acidic or neutral. This classification is determined by the ionic or covalent nature of the bonding in the oxide compound.
Are all oxides acidic?
No. A number of metal oxides are basic.
Are metals oxides acidic?
No, metal oxides are basic in nature.
Which oxides are acidic and which oxides are basic?
Sodium oxide, magnesium oxide, and copper oxide are basic oxides, while carbon dioxide, sulfur dioxide, and silicon dioxide are acidic oxides.
Is carbon dioxide an acidic gas?
Yes it is. All the oxides of non-metals are acidic and oxides of metals are basic
What type of oxides are formed when metals combine with oxygen?
acidic oxides
Is sulfur dioxide gas basic or acidic in nature?
sulphur dioxide is an acidic gas. Remember;- Groups 1 & 2 oxides are basic. None metal oxides are acidic.
What is another name for non-metallic oxides?
They are also known as acidic oxides since they form acidic solutions in water.
Classification of oxides?
Oxides are classified into 3 types: > Basic oxide > Acidic oxide > Amphoteric oxide (both Basic and Acidic)
What type of oxides are formed when non metals combine with oxygen?
acidic oxides
