Which compound would you expect to have the highest melting point?



BeO

MgO

CaO

SrO

  • chemistry - ,

    The one with the greater electronegativity difference. Electronegativity increase up and to the right of the periodic table, so the atom that is attached to O with smallest electronegativity should be the one with the highest melting point. But I am not 100% positive.


    SrO is my choice.
