if the valency of h2 is +1 then why sometimes it forms ionic hydrides? it means tht this disobeying the rule that in order to be stable, elements gain or loose electrons to get the nearrest noble gases' electronic configuration. to form an ionic hydride, it will donate one last valence ints shell, so how is nearest noble gase,helium(electronic con.= 2) is reached. but this is not like that. why? pls explain
