The chemistry of nobelium is practically unknown; but a reaction with magnesium can be estimated as impossible.
2H+ + Mg ------>H2 + Mg2+
MgBr2 magnesium bromide is ionic
Mg + 2H+ --> Mg2+ +H2
Magnesium carbonate is an ionic compound.
Because magnesium has a low electronegativity and chlorine has a high electronegativity, magnesium tends to lose an electron and chlorine tends to gain an electron when these substances react. This results in the formation of magnesium and chloride ions. Thus, magnesium chloride is ionic.
Nobelium have valences +2 and +3.
Nobelium form ionic bods.
2H+ + Mg ------>H2 + Mg2+
MgBr2 magnesium bromide is ionic
The chemical equation is:Mg + H2SO4 = MgSO4 + H2
Mg + 2H+ --> Mg2+ +H2
Magnesium oxide is ionic.
Magnesium carbonate is an ionic compound.
Because magnesium has a low electronegativity and chlorine has a high electronegativity, magnesium tends to lose an electron and chlorine tends to gain an electron when these substances react. This results in the formation of magnesium and chloride ions. Thus, magnesium chloride is ionic.
Ionic
Magnesium and iodine react to form the ionic compound magnesium iodide - MgI2.
Magnesium chloride is a compound, not a bond of any kind. The compound is ionic.
