Diatomic, the same as most other elemental gasses (the main exception being the monoatomic molecules of the Noble Gasses).
A hydrogen bond is the type of bond that attracts an oxygen and hydrogen molecule. In a hydrogen bond, the hydrogen atom from one molecule is attracted to the electronegative oxygen atom of another molecule.
A molecule consists of many atoms. When you have a hydrogen molecule, or whatever other type of molecule for that matter, you have many hydrogen atoms that make it.
Hydrogen is an element because it is made up of only one type of atom, which is hydrogen itself. When two hydrogen atoms bond together, they form a hydrogen molecule (H2). So, hydrogen can exist as both an element and a molecule.
A hydrogen bond. It is a type of weak chemical bond that forms between the positively charged hydrogen atom of one molecule and a more electronegative atom (commonly oxygen or nitrogen) of another molecule.
A hydrogen bond.
A hydrogen bond.
It is called hydrogen bond.
The hydrogen iodide is an acid with polar covalent bond.
A hydrogen bond.
A hydrogen bond.
A hydrogen bond is formed between the proton (H+) and the ammonia molecule (NH3). In a hydrogen bond, the hydrogen atom of one molecule is attracted to the electronegative atom of another molecule.
The type of intermolecular force present in KOH is hydrogen bonding. Hydrogen bonding occurs between the hydrogen atom of one molecule and the oxygen atom of another molecule when hydrogen is bonded to a highly electronegative atom such as oxygen.
