What is the relationship between the bonding in oxides and the type of oxide formed?
The bonding in oxides is primarily determined by the electronegativity difference between the elements involved. In ionic oxides, such as those formed by alkali and alkaline earth metals with oxygen, there is a significant electronegativity difference, leading to electron transfer and the formation of ionic bonds. In contrast, covalent oxides, like those formed by nonmetals (e.g., silicon dioxide), exhibit sharing of electrons due to smaller electronegativity differences. Thus, the nature of the bonding directly influences the properties and types of oxides formed, such as their melting points, solubility, and reactivity.

How can the classification of oxides be related to their metallic and non-metallic character?
Non-metallic oxides are acidic (Except hydrogen, oxygen, helium, neon, argon) whereas metallic oxides are generally amphoteric or alkali (Except chromium, molybdenum, tungsten, niobium, tantalum, technetium, rhenium, ruthenium, osmium, bismuth)
What is the general name of compounds that are formed in reactions of elements with oxegyn?
The general name of compounds formed in reactions of elements with oxygen is "oxides." These compounds can include a variety of substances, such as metal oxides and non-metal oxides, depending on the nature of the element reacting with oxygen. Oxides can exhibit different properties and behaviors based on their composition and the elements involved.
What is formed when an element is burned in air or oxygen?
When an element is burned in air or oxygen, it forms oxides. The type of oxide formed depends on the reactivity of the element with oxygen. For example, carbon forms carbon dioxide while magnesium forms magnesium oxide.
What happen when iron reacts with salt water?
Rust ( iron hydrated oxides) are formed.
How does the acid-base nature of the oxides in the period 3 change with the increasing atomic number?
The acidity of oxides generally decreases across period 3 from left to right. The oxides of elements on the left side, like sodium and magnesium, are basic (alkaline), while the oxides of elements on the right side, like sulfur and chlorine, are acidic. This trend is due to the change in bonding characteristics as the elements progress from metals to nonmetals across the period.
What is the difference between metallic and non metallic oxides?
Metallic oxides are formed by the reaction of a metal with oxygen and tend to be basic in nature, while non-metallic oxides are formed by the reaction of a non-metal with oxygen and can be acidic, neutral, or basic. Metallic oxides typically conduct electricity, while non-metallic oxides do not.
What type of oxides are formed by chemicals?
All the types of oxides !
What type of oxides are formed when metals combine with oxygen?
acidic oxides
What is a covalent oxide?
A covalent oxide is a compound formed between a nonmetal and oxygen in which the bonding involves the sharing of electrons, resulting in a covalent bond. These oxides typically have lower melting and boiling points compared to ionic oxides. Examples include carbon dioxide (CO2) and sulfur dioxide (SO2).
The name for most ionic compounds other than oxides?
A "salt" is another name for ionic compounds
How can the classification of oxides be related to their metallic and non-metallic character?
Non-metallic oxides are acidic (Except hydrogen, oxygen, helium, neon, argon) whereas metallic oxides are generally amphoteric or alkali (Except chromium, molybdenum, tungsten, niobium, tantalum, technetium, rhenium, ruthenium, osmium, bismuth)
Which of these is formed by combining oxygen with metals?
Oxides are formed by combining oxygen with metals. Oxides are compounds that contain at least one oxygen atom bound to one or more metal atoms. This process is known as oxidation.
What are metal oxides with examples?
Metal oxides are compounds formed between a metal and oxygen. Common examples include iron oxide (rust), aluminum oxide (corundum), and copper oxide. These oxides typically have a solid crystalline structure and are often used in various industrial applications.
What are formed when non metals combine with oxygen?
Oxides are formed when nonmetals combine with oxygen.
What is formed when nitrogen combines with oxygen when burning fossil fuels?
Various nitric oxides are formed.
This type of compound is usually formed when you burn an element in air?
Oxides are the type of compound that is typically formed when an element is burned in air. Oxides are compounds composed of an element combined with oxygen.
What is the chemical formula for oxides?
The chemical formula for oxides is typically written as O followed by the oxidation state of the other element, such as CO for carbon monoxide or Fe2O3 for iron(III) oxide. Oxides are compounds formed between oxygen and another element.
