Recent experimental observation of magicity in $^{78}$Ni has infused theinterest to examine the persistence of the magic character across the N$=$50shell gap in extremely neutron rich exotic nucleus $^{78}$Ni in ground as wellas excited states. A systematic study of Ni isotopes and N$=$50 isotones inground state is performed within the microscopic framework of relativisticmean-field (RMF) and the triaxially deformed Nilson Strutinsky model (NSM).Ground state density distributions, charge form factors, radii, separationenergies, pairing energies, single particle energies and the shell correctionsshow strong magicity in $^{78}$Ni. Excited nuclei are treated within thestatistical theory of hot rotating nuclei where the variation of level densityparameter and entropy shows significant magicity with a deep minima at N$=$50,which, persists up to the temperatures $\approx$ 1.5$-$2 MeV and then slowlydisappear with increasing temperature. Rotational states are evaluated andeffect of rotation on N$=$50 (Z$=$20$-$30) isotones are studied. Our resultsagree very well with the available experimental data and few other theoreticalcalculations.
