Mendeleev used hydrides and oxides for the classification of elements because these compounds exhibit systematic trends in properties that correlate with the atomic weights of the elements. By analyzing the properties of hydrides and oxides, he could identify patterns in reactivity, molecular structure, and oxidation states, which helped him establish a coherent arrangement of elements in his Periodic Table. This approach allowed Mendeleev to predict the existence and properties of undiscovered elements, reinforcing the periodic law.
What else can I help you with?
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)
When the elements in the periodic table react with different things such as hydrogen oxygen halogens and water do they always create hydrides oxides halides and hydroxides?
The -ide suffix basically means that 2 elements are combining. For example, sodium(Na) and chlorine (Cl) chemically react to form Sodium chloride. Notice how chlorine changes to chloride?? It means two elements are reacting.
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.
All hydrides liberate what during decomposition?
During decomposition, most hydrides liberate hydrogen gas (Hâ‚‚). This occurs as the hydride breaks down, releasing hydrogen while often forming other compounds, such as metal oxides or acids, depending on the specific hydride. The liberation of hydrogen is a characteristic feature of many hydride compounds.
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 are 5 examples of substance?
oxides, halides, hydrides
How did Mendeleev organize the elements to create the periodic table?
Mendeleev organized the elements according to their increasing atomic masses and considered their fundamental properties . He also considered the Hydrides and Oxides formed by the elements.
What kinds of compounds do metals ussually forms?
Ex.: oxides, sulphides, nitrides, carbides, hydrides, selenides, arsenides, borides, oxides, hydroxides, etc.
What are the two elements which form acidic oxides?
Nonmetal elements such as sulfur and nonmetal oxides like carbon dioxide form acidic oxides.
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)

How did mendeleev organize the elements to create a periodic table?
Mendeleev organized the elements by increasing atomic mass and grouping elements with similar properties into columns called groups. He left gaps in the table for undiscovered elements and predicted properties of these elements based on the periodic pattern of known elements.
What elements can chemically combines with plutonium?
Plutonium can chemically combine with elements such as oxygen, chlorine, hydrogen, and nitrogen to form various compounds. It is known to form oxides (such as PuO2), halides (such as PuCl3), hydrides (such as PuH2), and nitrides (such as PuN).
Are sulfur carbon and oxygen oxides?
Yes, sulfur, carbon, and oxygen can form oxides. Sulfur oxides (such as sulfur dioxide and sulfur trioxide), carbon oxides (such as carbon monoxide and carbon dioxide), and oxygen oxides (such as ozone) are all compounds formed by the combination of these elements with oxygen.
Does plutonium react with anything?
Plutonium can react with many elements, forming compounds such as oxides, halides, and hydrides. It is highly reactive and can undergo reactions such as oxidation, reduction, and complexation with various ligands. These reactions are important in nuclear processes and research involving plutonium.
Acid rain is composed mainly of the oxides of two elements give either?
sulfur oxides (SOx) and nitrogen oxides (NOx)
