I'm assuming you mean

Each hydrogen atom contributes one

If you calculate their bond order, you get:

#"BO"_(H_2^(+)) = 1/2("Bonding" - "Antibonding")#

#= 1/2(1-0) = 1/2#

#"BO"_(H_2^(-)) = 1/2("Bonding" - "Antibonding")#

#= 1/2(2-1) = 1/2#

So, neither is more stable than the other. But of course, they are less stable than
