Hydrogen forms some ionic and some covalent bonds - depending on its partner
EN for H is 2.2
En increase across the rows in the Periodic Table
Ionic bonds form between compounds with large differences in EN
Colalent bonds form between molecules with similar ENs
so (As a general rule of thumb) going across the periodic table it will first form ionic bonds then covalent molecular
From the Wikipedia article: Hydrogen Bond, "A hydrogen bond is the attractive interaction of a hydrogen atom with an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule or chemical group. The hydrogen must be covalently bonded to another electronegative atom to create the bond. These bonds can occur between molecules (intermolecularly), or within different parts of a single molecule (intramolecularly)."
A hydrogen bond is never ionic, as it does not involve the transfer of electrons neither is it covalent, as it does not involve the sharing of electrons.
No, the bond between hydrogen and oxygen is polar covalent due to the electronegativity difference
No. It contains two different types of bonds, neither is ionic.
No, hydrogen bonds are still weaker than ionic bonds. They are technically a type of intermolecular force rather than and actual bond.
No, It is a covalent bond
its a ionic bond
Ionic bonds, covalent bonds, and probably hydrogen bonds
ionic bonds
Covalent bonds form molecules where ionic bonds form ionic lattices. Hydrogen bonds are a form of intermolecular bonds which are formed with the participation of polar hydrogen atoms which are attached to either nitrogen, oxygen or fluorine.
It is not covalent, because it is the strongest type. The Correct answer is van der Waals.
convalent
Hydrogen is involved in covalent bonds but sometimes also in ionic bonds.
The two main types of chemical bonds are ionic and covalent.
Ionic bonds, covalent bonds, and probably hydrogen bonds
ionic bonds
No, hydrogen bonds are weak in comparison to both ionic and covalent bonds.
Hydrogen bonds with hydrogen bond acceptor atoms such as Oxygen. Covalent bonds with nearly anything.
Covalent bonds form molecules where ionic bonds form ionic lattices. Hydrogen bonds are a form of intermolecular bonds which are formed with the participation of polar hydrogen atoms which are attached to either nitrogen, oxygen or fluorine.
It is not covalent, because it is the strongest type. The Correct answer is van der Waals.
convalent
No they are significantly weaker.
Hydrogen Chloride (the gas) has covalent bonds, but Hydrochloric acid forms ionic bonds. As to why this occurs, I am clueless
Hydrogen bonds, Ionic bonds, and Polar bonds!
