Hence, no bond between Ne atoms.
Answer:
Molecular orbital diagram of
Explanation:
- Neon atom has 10 electrons and its electronic configuration is . When molecule is considered, it has two neon atoms and thus is composed of 20 electrons.
- As the bond order value for molecule is zero, it is unstable and cannot exist.
- The molecular orbital diagram of hypothetical molecule is given in the attachment.
