A display models an H–Cl molecule. The original bond has two shared electrons. It can erase the bond in either of two ways. In model P, each atom keeps one electron from the bond. In model Q, chlorine keeps both. A neutral H atom has one electron. A neutral Cl atom has 17 electrons. Seven of the electrons in a neutral chlorine atom are valence electrons.
| Model | Bond electrons H keeps | Bond electrons Cl keeps |
|---|---|---|
| P | 1 | 1 |
| Q | 0 | 2 |
Question 1
Which model gives H a +1 charge?
- P only
- Q only
- Both models
- Neither model
Question 2
Compare the individual fragment charges and their combined charge in both models.
