Oxidation number What are oxidation numbers of each element in CuH?

My chemistry teacher said Hydrogenhydrogen when bonded with metals, shows Oxidation state has oxidation number (O.N.) of −1 -1 exceptexcept CuH. In: in CuH, Hydrogen the hydrogen has oxidation state ofO.N. +1 & Copperand the copper has -1O.N. −1.

But on the internet, it is showingubiquitously told that Hydrogen has oxidation statethe O.N. of -1hydrogen is −1 in CuH too, and the compound's name is copper(I) hydride. I am confused which one is correct.

If Hydrogenhydrogen has Oxidation stateO.N. of +1 in CuH, why is it so?

Thanks
