When alkali metals are heated with hydrongen they form?
we call them hydrides. Hydrides are forming by the reaction.
How do you classify hydrides?
Hydrides can be classified based on their ionic or covalent nature, with ionic hydrides containing hydride ions (H-) and covalent hydrides formed through sharing of electrons. Hydrides can also be categorized as interstitial or bonded hydrides based on their structure and bonding characteristics. Additionally, hydrides can be classified as metallic, non-metallic, or interstitial hydrides based on the nature of the element involved in hydride formation.
Why are the elements of group 6 called hydrides?
The elements of group 6 (chromium, molybdenum, tungsten, and seaborgium) are called hydrides because they can form compounds with hydrogen known as hydrides. These hydrides typically exhibit metallic or covalent behavior depending on the element and its oxidation state, making them a distinct group within the periodic table.
When alkali metals are heated with hydrogen they form?
They form alkali metal hydrides. such as LiH and NaH.
Does beryllium react with cold water?
Be (beryllium) does not react with water , steam or oxygen even at red heat. because it has a strong resistant layer of oxide on it's surface (impenetrable coating)which lower it's reactivity.
Why ionic hydrides are called true hydrides?
Ionic hydrides are called true hydrides because they are formed by the direct combination of hydrogen with an electropositive metal, resulting in a compound with characteristics typical of hydrides. These hydrides exhibit ionic bonding between the metal cation and the hydrogen anion, hence the name "ionic hydrides".
What are the differences between Ionic Hydrides and Covalent hydrides?
Ionic hydrides are formed between metals and hydrogen, where hydrogen gains an electron to form the hydride ion. Covalent hydrides are formed between nonmetals and hydrogen, where they share electrons to form covalent bonds. Ionic hydrides are typically solid at room temperature, while covalent hydrides can be gases, liquids, or solids.

Why are Alkai and Alkaline earth metal hydrides are called true hydrides?
because aklai are soluble in water with compltely and alkai earth metal are partially dissolve in water thats they are called true hydrides

When the sign of hydrogen is negative?
In hydrides.
Acid and metal produces?
metal hydrides
Which substances have a negative hydrogen?
all hydrides
Why Be and Mg form polymeric hydrides and not ionic hydrides?
Beryllium and magnesium have high charge density and small atomic size, making it energetically more favorable for them to form covalent bonds with hydrogen atoms to create polymeric hydrides. The formation of ionic hydrides would require a stronger electron transfer, which is less favorable due to the large ionization energy of these metals.
When is H in negative oxidation state?
Hydrogen can exhibit a negative oxidation state in compounds known as hydrides, where it gains an electron to become H-. Some examples include metal hydrides like sodium hydride (NaH) and covalent hydrides like borane (BH3).
Definition of uses of covalent and ionic hydride?
Covalent hydrides are compounds containing hydrogen bonded to nonmetals through covalent bonds, such as methane. Ionic hydrides are compounds where hydrogen is bonded to a highly electropositive metal through ionic bonds, such as sodium hydride. Covalent hydrides are typically non-metallic and have lower melting and boiling points, whereas ionic hydrides are generally more reactive due to the presence of highly electrostatic interactions.
