When alkali metals are heated, they react with oxygen to form various oxy compounds, primarily metal oxides (e.g., sodium oxide, Na2O, and potassium oxide, K2O). In some cases, they can also form peroxides (e.g., sodium peroxide, Na2O2) and superoxides (e.g., potassium superoxide, KO2), depending on the specific metal and the reaction conditions. These compounds exhibit distinct properties and reactivity based on the oxidation state of the metal and the type of oxygen species involved.
When alkali metals are heated, they react with oxygen to form various oxy compounds, primarily metal oxides. For example, lithium forms lithium oxide (Li2O), sodium forms sodium oxide (Na2O), and potassium forms potassium oxide (K2O). These reactions are typically highly exothermic and result in the formation of stable ionic compounds. Additionally, alkali metals can also form peroxides and superoxides under specific conditions, particularly in the case of sodium and potassium.

They form alkali metal hydrides. such as LiH and NaH.
we call them hydrides. Hydrides are forming by the reaction.
No, covalent bonds are not typically formed between alkali metals and non-metals. Alkali metals usually lose an electron to form positive ions, while non-metals gain electrons to form negative ions which are held together by ionic bonds.

Alkali metals have a +1 oxidation state and form compounds with a 1:1 ratio of metal to other element, while alkaline earth metals have a +2 oxidation state and form compounds with a 1:2 ratio. By analyzing the stoichiometry of compounds formed with these metals, you can distinguish between alkali metals and alkaline earth metals.
by metals
generally known as metal hydroxides or basic salts. They are formed when active metals (like alkali metals or alkaline earth metals) react with hydroxide ions to form compounds with a basic pH. These compounds are often used in various industrial processes and as alkaline reagents.
They form alkali metal hydrides. such as LiH and NaH.
An ionic bond is formed by electron transfer between alkali metals and halogens.

NONE!!! They all react and dissolve in water. However, on going down the Group from lithium to francium , the dissolution becomes more an more violent from a gentle fizz (lithium) to explosion (francium). Francium is NOT found in an 'open' lab. because it is also radio-active. Because you can't have explosive material spraying radio-active matter everywhere in an uncontrolled manner.
All alkali metals exist in nature as compounds.
