Colvalent because they are all non-metals
Formula: CdBr2
Cadmium Bromide
CdBr2 + Na2S --> CdS + 2NaBr.
If it's a non-metal and non-metal, it is a colvalent bond. If it's metal and non-metal or metal and metal, then it is ionic. Magnesium Sulfate (MgSO4 / Magnesium + Sulfate) is IONICbecause it is a metal and non-metal but it has a convalent bond in it, which is SO4 (Sulfur + Oxygen).

it depends on the reactant. and the bond could be colvalent, ionic, coordinate, hydrogen bond or a mixture of these.
If it's a non-metal and non-metal, it is a colvalent bond. If it's metal and non-metal or metal and metal, then it is ionic. Magnesium Sulfate (MgSO4 / Magnesium + Sulfate) is IONICbecause it is a metal and non-metal but it has a convalent bond in it, which is SO4 (Sulfur + Oxygen).
Polar Colvalent
IONIC: Na+ ion and (OH)- ions are held together by strong ionic bonds. COVALENT: O2- and H+ ions are held together by colvalent bonds. therefore sodium hydroxide is contains both covalent and ionic bonds. but generally we say that NaOH is an ionic compound. =)
the difference is thatcovelent bonds share electrons, thus creating bonds, the only reason they share electrons so that they can get full outer shells. Ionic bonds like....They bond between two different things, like a non metal, and a metal
PCl3 would not be ionic because is isn't between a metal and a non metal. Thus, it would be predominantly covalent. It has a trigonal pyrimidal shape, and is POLAR. So, the answer ispolar covalent.
The reaction is:Cd + 2 HBr = CdBr2 + H2
If it's a non-metal and non-metal, it is a colvalent bond. If it's metal and non-metal or metal and metal, then it is ionic. Magnesium Sulfate (MgSO4 / Magnesium + Sulfate) is IONICbecause it is a metal and non-metal but it has a convalent bond in it, which is SO4 (Sulfur + Oxygen).
