Which type of bond is present between hydrogens in hydrogen molecule?a...
Explanation:
The type of bond present between the two hydrogen atoms in a hydrogen molecule is a Sigma bond.
Sigma bond:
- A sigma bond is formed when two atomic orbitals overlap head-on, resulting in the sharing of electrons between the two atoms.
- In a hydrogen molecule, each hydrogen atom contributes one electron to form a covalent bond.
- The overlap between the two 1s orbitals of the hydrogen atoms leads to the formation of a sigma bond.
- The sigma bond is a strong bond that holds the two hydrogen atoms together in the molecule.
Pi bond:
- A pi bond is formed when two p orbitals overlap sideways or parallel to each other.
- In a hydrogen molecule, there are no p orbitals involved in the bonding, so there is no pi bond present.
Ionic bond:
- An ionic bond is formed between a metal and a non-metal, where one atom donates electrons to another atom.
- In the case of a hydrogen molecule, both hydrogen atoms are non-metals, so an ionic bond is not present.
Metallic bond:
- A metallic bond occurs between metal atoms, where the valence electrons are delocalized and shared among all the atoms in a metal lattice.
- Hydrogen is not a metal, so a metallic bond is not present in a hydrogen molecule.
In conclusion, the bond between the hydrogen atoms in a hydrogen molecule is a sigma bond formed by the overlap of their 1s atomic orbitals.

The head-on or end to end type of overlapping is present in sigma bond. A sigma bond is a type of covalent bond. It may also be called an axial overlap. In case of the hydrogen molecule, its s-s overlapping.
