Why basic nature of oxides increase down the group?
Since the oxides of non-metals are acidic. Thus it can be said, along a period from left to right basic character decreases while on moving downward, the basic character increases due to an increase in metallic character.
Why acidic strength of oxides decreases down the group?
As we all know, electronegativity is an element’s ability to attract electron pairs. As a result, because the electronegativity decreases down the group, the acidic character of the oxides “decreases down the group.” Similarly, more electropositive metals have more basic oxide in their natural state.
What is the nature of oxide in nature?
Oxides of non – metals are acidic, while the oxides of metals are basic in nature as they produce bases, like Na2O+H2O→2NaOH, oxide of sodium produces sodium hydroxide which is a base.
How does the nature of oxides change in a period?
The oxides of metals are basic, while those of non-metals are acidic. On moving from the left to the right in a period, the metallic character of the elements decreases, while the non-metallic character increases.
How does the nature of oxides of the elements change on moving from top to bottom in a group of the periodic table give example?
Solution : As the electronegativity of element increases, acidic character of oxides increases. So, in a group, basic nature increases on moving down and decreases along a period.
Why there is no change in nature of oxides down the group?
When its an element of group 13 – 18, it has a tendency to have more of non metallic character ( since, metallic character decreases left to right across a period). Those elements form acidic oxides (non metals). Therefore, on going down a group of periodic table, there is no change in nature of oxide of elements.
Why does the acidic character of oxides decrease down the group 16?
Acid-base properties:The acidic character of oxides of group 16 elements decreases as we move down the group. Reducing-oxidising properties: Since +6 oxidation state of sulphur is more stable than +4 oxidation state, therefore, SO2 acts as a reducing agent.
What is the nature of oxides in groups and periods?
What is the nature of oxides along groups and periods in the modern periodic table? Oxides of metal are of basic nature while those of non metals are acidic. This means that along the period, the basic character of the oxides of the elements decreases while their acidic character increases.
What are the nature of oxide for class 10th?
Answer: Oxides of metals are basic in nature while oxides of non metals are acidic in nature.
How does nature of oxides vary along period and down the group?
Periodic Classification of Elements Oxides of metal are of basic nature while those of non metals are acidic. This means that along the period, the basic character of the oxides of the elements decreases while their acidic character increases. On going down in the group of a periodic table, the order is reversed.
What is the variation of nature of oxides in a group?
Solution : Variation of nature of oxides in the Group – 1 :All the elements of IA group are called alkali metals. These oxides are basic in nature. They dissolve in water giving alkaline solutions `Na_(2)O + H_(2)O rarr 2NaOH` The basic nature of these oxides increases from top to bottom in group – 1 elements.
What happens to nature of oxides and Valency as we move across a period and group?
NATURE OF OXIDES: On moving from left to right in a period, the basic nature of oxides decreases and the acidic nature of oxides increases. Ongoing down in a group of the periodic table, there is no change in the nature of oxides of element.
How nature of oxides varies in the group and period?
Solution : The basic nature of the oxide decreases in a period while acidic nature increases. In a group, basic nature of the oxide increases, while acidic nature decreases.
Why does the oxidising power of the oxides increases down the group 16?
Answer. Answer: As we move from left to right, the electronegativity of elements increases, so they have less tendency to lose electrons and non-metallic character of elements increases. So as the non-metallic character increases so oxidizing power of elements increases from left to right along a period.
What happens to the basic characters of oxides down the group and why?
As we know that electronegativity is the property of the element to attract electron pairs. Hence, the acidic character of the oxides “decreases down the group” because the electronegativity decreases down the group. Similarly, when the metal is more electropositive, it has more basic oxide in nature.
Why oxidation state decreases down the group?
The tendency to exhibit -3 oxidation state decreases as we move down the group due to an increase in the size of the atom and the metallic character.
Why does oxidising increase from left to right?
Oxidising power means to accept electrons. As we move from left to right along a periodic table the size of element decrease hold of nucleus increases incoming electron is accepted easily thus oxidising power of element increases.
Why does the stability of oxidation state +3 of group 15 elements increase on moving down the group?
The stability of +3 oxidation state increases down the group due to inert pair effect which is defined as follows:The reluctance of the s electrons to take part in the chemical bonding due to which the lower oxidation states become more stable on descending down the group of p-block elements is known as inert pair …
Which oxidation state is more stable?
– That’s why the oxidation state of +3 is the most stable oxidation state than the +4, +2 and +6 oxidation states.
Why does oxidizing power decreases down the group?
Further down the Group, the halogens gain electrons less easily. Halogens don’t tend to lose electrons. If you’re doing GCSE I don’t think you need to know about Halogens losing electrons though. So they are reduced less easily therefore oxidising power decreases.
Why do oxides increase in nature down the column?
In the inert gases elements, only xenon forms oxides, and they are acidic. Down the column, elements become more electropositive and hence form stronger basic oxides. Basic nature of the oxides increases down the column in any group.
What is the nature of oxides?
Nature of oxides as acidic, basic, amphoteric and neutral. Binary oxygen compounds containing electropositive metals are metallic oxides, while, those having nonmetals are non-metallic oxides. Metallic oxides: A chemical compound formed by metal and oxygen. Nonmetallic oxides: In the air, nonmetal reacts with oxygen to produce nonmetallic oxides.
What are the neutral oxides of oxygen?
Neutral Oxides: Some compounds react with oxygen to form oxides which do not exhibit acidic nor basic characteristics. Such compounds are called as neutral compounds of oxygen. Example: NO, CO.

What are oxides of oxygen called?
Of the oxygen compounds, binary compounds of oxygen with lesser electronegative elements are called oxides. Fluorine is the only element having large electronegativity than oxygen.
