In the formation of hydrogen molecule, overlapping of atomic orbitals ...
In the formation of a hydrogen molecule, the overlapping of atomic orbitals results in the pairing of electrons.
Explanation:
1. Atomic orbitals:
- Before we discuss the formation of a hydrogen molecule, let's understand what atomic orbitals are.
- Atomic orbitals are regions of space around an atomic nucleus where an electron is likely to be found.
- In the case of hydrogen, each hydrogen atom has one electron which occupies its atomic orbital.
2. Overlapping of atomic orbitals:
- When two hydrogen atoms come close to each other, the atomic orbitals of their electrons start to overlap.
- The overlapping occurs between the 1s orbitals of the two hydrogen atoms.
3. Formation of a covalent bond:
- As a result of the overlapping, a covalent bond is formed between the two hydrogen atoms.
- A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.
- In the case of hydrogen, the two hydrogen atoms share their electrons to complete their respective valence shells.
4. Valence shell electrons with opposite spins:
- In the process of forming a covalent bond, the electrons from the valence shell of each hydrogen atom participate.
- The valence shell is the outermost shell of an atom that contains electrons.
- In the case of hydrogen, the valence shell consists of a single 1s orbital.
- The two electrons in the 1s orbital of each hydrogen atom have opposite spins, represented as ↑ and ↓.
5. Pairing of electrons:
- During the formation of a hydrogen molecule, the overlapping of the 1s orbitals results in the pairing of electrons.
- The two electrons from the valence shell of each hydrogen atom come together and occupy a shared orbital.
- These paired electrons have opposite spins, fulfilling the requirement for Hund's rule, which states that electrons will occupy separate orbitals with the same spin before pairing up.
Therefore, the correct answer is option 'D' - valence shell electrons with opposite spins.
