    Are metals hydrides simple covalent substances and thus do they have a simple molecular lattice ?

    On the electronegativity scale,

    metals tend to be electropositive, hence on the low electronegativity (EN) scale

    non-metals tend to be highly electronegative, the opposite end

    think of hydrogen's EN as somewhere in between

    Where you have atoms of similar EN bonding together, they are most likely to form covalent bond (sharing of electrons instead)
    ie C-H, N-H, O-H and so on

    Where you have atoms of extremely different EN bonding together, they are most likely to form ionic bond instead, giving you ions.

    In terms of oxidation numbers, hydrogen is usually +1 in most compounds except in hydrides (when bonded with metal cations) when H is -1

    Metal hydrides have giant ionic lattice structure. it consists of metal cations and hydride (hydrogen with single negative charge - hence 1 proton, 0 neutron, 2 electrons).
