Determine the oxidation state of hydrogen in the following compounds H2S, NaH, H2, Hl

Determine the oxidation state of hydrogen in the following compounds: H2S, NaH, H2, Hl.
The oxidation state is an auxiliary conditional value for recording the processes of oxidation, reduction and redox reactions.
H2S – the oxidation state of hydrogen is +1, the oxidation state of sulfur is 2.
NaH – oxidation state of sodium + 1, hydrogen – 1.
H2 – the oxidation state of hydrogen is 0.
НI – the oxidation state of hydrogen is +1, the oxidation state of iodine is -1.
