Does He2 exist?
Understand the Problem
The question is asking whether the diatomic helium molecule (He2) exists, which relates to concepts in chemistry and molecular physics.
Answer
He2 molecule does not exist due to zero bond order.
The He2 molecule does not exist because, according to molecular orbital theory, its bond order is zero, meaning no bond forms between the two helium atoms.
Answer for screen readers
The He2 molecule does not exist because, according to molecular orbital theory, its bond order is zero, meaning no bond forms between the two helium atoms.
More Information
Helium atoms have full electron shells making them stable. When using molecular orbital theory, it shows no net bonding interaction due to equal numbers of bonding and antibonding electrons.
Tips
A common mistake is not using molecular orbital theory to explain bond order. Always use it to correctly determine if bonds form.
