What does the 2 indicate in the formula mgbr2?

The "2" in MgBr2 indicates that magnesium (Mg) forms an ionic compound with two bromide ions (Br-). This means that magnesium will have a 2+ charge to balance the 2- charge of the two bromide ions.


Is mgbr2 covalent ionic or metallic?

MgBr2 is an ionic compound. Ionic compounds are formed through the transfer of electrons between a metal and a non-metal, resulting in attraction between positively and negatively charged ions. In the case of MgBr2, magnesium (metal) loses two electrons to bromine (non-metal), forming Mg2+ and 2Br- ions.
