KH is the alkali metal hydride and a crystalline solid, in molten state it conducts electricity as it possesses K+ and H− ions.
Can metal hydride conduct electricity?
Answer: (a, b, c) Metal hydrides are not only deficient of hydrogen but they are good conductor of heat and electricity in molten state.
Which of the following hydrides Cannot conduct electricity?
The answer is the option (i), (ii), and (iii) Metallic hydrides are deficient of Hydrogen, Metallic hydrides conduct heat and electricity, and Ionic hydrides do not conduct electricity in solid-state.
Are ionic hydrides good conductors of electricity?
Ionic hydrides are very good conductors of electricity in solid state.
Does ionic hydrides conduct electricity in liquid state?
In liquid state or molten states, ionic hydrides are electrolyzed and conduct electricity by liberating hydrogen gas at the anode.
Do ionic hydrides conduct electricity in solid state?
Ionic hydrides do not conduct electricity in solid state.
Which of the following compound can conduct electricity?
CaCl2 or Calcium Chloride will conduct electricity as it is an ionic compound. Ionic compounds have high melting and boiling points and conduct electricity in a molten state. Ionic compounds are soluble in water and insoluble in polar covalent.
Which of the following hydrides conduct electricity in fused and aqueous state?
Sodium chloride will conduct electricity only in fused or aqueous state.
Are metal hydrides ionic?
A hydrogen compound that forms a bond with another metal element is classified as a metal hydride. The bond is mostly covalent type but sometimes the hydrides are formed with ionic bonds.
Do molecular hydrides conduct electricity?
Properties of Molecular or Covalent Hydrides
1) Covalent hydrides are usually volatile compounds having low melting and boiling point and also do not conduct electricity.
What are metallic hydrides give examples?
The most common examples of metal hydrides include aluminum, boron, lithium borohydride and various salts. For example, aluminum hydrides include sodium aluminum hydride.
Is Nah a conductor?
Pure sodium (Na) is a good conductor of electricity because the 3s and 3p atomic bands overlap to form partially filled conduction bands. By contrast the ionic sodium chloride (NaCl) crystal is: … Conductor.
What are covalent hydrides?
Covalent hydrides are primarily compounds of hydrogen and nonmetals, in which the bonds are evidently electron pairs shared by atoms of comparable electronegativities. … Covalent hydrides can be formed from boron (B), aluminum (Al), and gallium (Ga) of group 13 in the periodic table.
Why metallic hydrides are non stoichiometric?
Metallic hydrides are usually nonstoichiometric compounds, as expected from their relatively low heats of formation and the mobility of hydrogen.
Which type of elements form ionic hydrides?
Group 1 and 2 elements form white crystalline, ionic hydrides. Their stability depends upon ionic character and lattice energy. Convalent hydrides are most common type of hydrides. Transition metals form interstitial hydrides.
