Why does $\ce{NO2}$ exists as a gas molecule, $\ce{NO2-},$ $\ce{NO2+}?$ How are they different in structure and reactivity?

I am confused how the same compound with same number of atom can have $+1,$ $0,$ $-1$ charge in different contexts. When it is a ligand it is $\ce{NO2-},$ during nitration of benzene it is $\ce{NO2+}$ and while manufacturing nitric acid it is $\ce{NO2}$ gas.

    $\begingroup$ This is what chemistry is about. Adding or removing even a single electron is a great deal and shouldn't really be that surprising. $\endgroup$ – andselisk Nov 8 at 6:30
