The table shows the electron arrangements of atoms of two elements, J and Q.
| Element | Electron arrangement |
|---|---|
| J | 2.8.3 |
| Q | 2.7 |
J and Q react to form an ionic compound. Only the outer-shell electrons are shown in its dot and cross diagram.
Explain what the dot and cross diagram of this compound should show.
