My teacher taught us that when
metal + non-metal = ionic bond
non-metal + non-metal = covalent bond
but then if according to electro-negativity, let say for Ca and H
i would contradicts between
metal (Ca) + H (non-metal) = ionic
but their difference in electro-negativity= 1.2 (lower than 1.6)
then THAT would be Covalent
Please explain

H has properties of a non metal .Since it has only 1 electron it can either give it or take 1 from another element>in the above case it gives its electron acting as a metal hence forming covalent bond {as also in the case of HCl}

Metal + nonmetal is ALWAYS ionic regardless of the difference in electronegativity.
