The table shows the electron arrangements of atoms P, Q and R.
| Atom | Electron arrangement |
|---|---|
| P | 2.8.2 |
| Q | 2.6 |
| R | 2.8.8 |
A student claims that P and Q will both lose electrons when they react, and that R will react in the same way as P and Q. Explain why the student is incorrect. In your answer, give the ions formed when P and Q react with each other and state what holds these ions together.
