Question 4
What does the symbol δ+ on a hydrogen atom represent?
The right answer is the one marked above.
A very small partial charge, much less than the charge on an ion. No electron has been transferred; the shared pair has merely been pulled off centre, leaving a slight imbalance.
A full +1 would mean an electron had been lost outright, making it an ion. Protons never move. And partial charges are a feature of polar covalent bonds, which is the opposite of an ionic compound.
