Each X will increase the oxidation number of metal by +1. Each L and X will supply 2 electrons to the electron count.

Each X will increase the oxidation number of metal by +1. Each L and X will supply 2 electrons to the electron count.

Each X will increase the oxidation number of metal by +1. Each L and X will supply 2 electrons to the electron count. Now looking at compounds having a charge of +1 to obey 18 e rule. Elec count: 4 (M) +2 (NO) +12 (L 6 ) = 18. NO + is isoelectronic to CO X increases O N by 1.
