A single bond involves the sharing of two electrons as is the case of water in between the hydrogen and oxygen each bond is single bond and contains 2 electrons. In a double the sharing of 4 electons as in alkenes or between oxygen and oxygen in O2 and in a triple 6 as in the nitrogen gas( N2)between N and N.
AnswerIt is a molecular compound
Ionic. It would have to bind to a non-metal to do this. It can't be covalent because covalent is non-metal to non-metal.
If it bonded to another metal though, it would be a metallic bond
it is formed by the electrostatic force of attraction between the localized shared electrons and the nuclei is called covalent bond !
The ionic character of NO3 is -1.
