There is no single answer to this question as different group one metals form different oxides. We would expect group one elements to form M2O oxides but in fact only lithium does this when burnt. The other elements more easily lose electrons from their second outermost shell so can form peroxides M2O2, superoxides MO2 or even higher oxidation state oxides. For example Caesium can form Cs7O.

Which metal oxides are insoluble in water and which are soluble?
Insoluble metal oxides generally include group II metal oxides like calcium oxide (CaO) and magnesium oxide (MgO). Soluble metal oxides often belong to group I metals like sodium oxide (Na2O) and potassium oxide (K2O), as well as transition metals like iron oxide (Fe2O3) and copper oxide (CuO).
Are metal oxides neutral?
Metal oxides can be basic, acidic, or amphoteric depending on the metal and the oxidation state of the metal ion. Basic metal oxides react with acid to form a salt and water, while acidic metal oxides react with base to form a salt and water. Amphoteric metal oxides can act as both an acid and a base depending on the reaction conditions.
What term can be used to describe non-metal oxides?
Non-metal oxides are often referred to as acidic oxides because they produce acidic solutions when they are dissolved in water. These oxides are typically formed by non-metal elements combining with oxygen.
Which type of oxide is formed when metals combine with oxygen?
Metal oxides form alkalis when they dissolve in water. Non-metal oxides for acids. For example: carbon dioxide + water --> carbonic acid magnesium oxide + water --> magnesium hydroxide
What do metal hydroxides decompose yield?
Metal hydroxides typically decompose to yield metal oxides and water through a process known as thermal decomposition. For example, when copper(II) hydroxide decomposes, it forms copper(II) oxide and water.
Is the BYU online General Chemistry Part 2 a difficult course?
The basicity of main group metal oxides increases on decending a group of periodic table though the reverse trend is observed in the transition metal oxides why?
What is metal oxide?
Metallic oxides are metal and oxygen, bonded together. They are generally solids, and have higher densities. An example of a metallic oxides is sodium, Na.
What do group 1 metals make when mixed with oxygen?
Group 1 metals, such as lithium, sodium, and potassium, form metal oxides when they react with oxygen. These metal oxides are typically white or colorless solids and are basic in nature.
Which metal oxides are insoluble in water and which are soluble?
Insoluble metal oxides generally include group II metal oxides like calcium oxide (CaO) and magnesium oxide (MgO). Soluble metal oxides often belong to group I metals like sodium oxide (Na2O) and potassium oxide (K2O), as well as transition metals like iron oxide (Fe2O3) and copper oxide (CuO).
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 mineral group contains compounds of oxygen and a metal?
Oxides are the mineral group that contains compounds of oxygen and a metal. These minerals typically form when metals react with oxygen to create stable compounds like hematite (iron oxide) and magnetite (iron oxide).
Is metal oxide an alkali?
Metal oxide is the ionic bond combination of any metal element of the periodic table of elements with oxygen. The alkali metals and alkali earth metals are respectively the first and second columns of elements found on the periodic table. Thus, alkali metal oxides and earth metal oxides are types of metal oxides, but metal oxide does not imply alkali.
In which group do the elements ussually orm oxides which have the general formula M2O3?
Group 3(III) Oxides of Group (I) are M2O Group (II) are MO Group(III) are M2O3 Group(IV) are MO2 Group(V) are M2O5 ( Can vary ; NO , N2O , NO2) Group(VI) are MO3 ( Can Vary ; MO2 MO3) Group(VII) are M2O7 ( Can Vary) Group(VIII) are ther Noble (Inert) gases and do not react. Transition metal/elements can exhibit variable oxidations from MO , M2O3, etcs., NB Group (V) , (VI), & (VII) have variable oxidation numbers and so can exhibit various oxides. NNB 'M' is used to indicate an element , not just a metal .
Are metal's oxides gases or bases?
Metal oxides are typically basic.
Is metal oxide is a base?
Metal oxides can act as bases because of their ability to accept protons. When metal oxides react with water, they can form metal hydroxides, which are basic in nature due to their ability to release hydroxide ions in solution.
Are metal oxides neutral?
Metal oxides can be basic, acidic, or amphoteric depending on the metal and the oxidation state of the metal ion. Basic metal oxides react with acid to form a salt and water, while acidic metal oxides react with base to form a salt and water. Amphoteric metal oxides can act as both an acid and a base depending on the reaction conditions.
What is the word equation for the reaction between acids and metal oxides?
The general word equation for the reaction between acids and metal oxides is: acid + metal oxide -> salt + water. The specific salt formed depends on the acid and metal oxide involved in the reaction.
