+2 for Mg and -1 for Br in magnesium bromide

What is the balanced equation when magnesium reacts with bromine?

Bromine is diatomic, so 2 atoms make up Bromine as a reactant. Mg + Br2 ----> MgBr2

What does 2 represents in the chemical formula MgBr2?

This means that there are two bromines in magnesium bromide, much like there are two hydrogens in water, H2O. This occurs because when magnesium forms an ion it has a charge of (+2), and when bromine forms an ion, it has a charge of (-1), Thus, it takes 2 bromines to neutralize the charge of the magnesium.

What is the balanced equation for copper 2 bromine?

copper 2 bromine is not a chemical name. copper and bromine are both elements. the term "copper 2" suggests divalent copper, ie copper in the Cu++ state. Bromine is almost always a monovalent anion, ie Br-. Copper bromide is then one copper ion and two bromine ions together forming CuBr2.

What substance are in bromine?

2 atoms of Bromine[Br] are in Molecular Bromine(Br2)

What does Mg2O stand for?

I believe it is Magnesium Oxide. The 2 should be subscript, denoting the presence of two atoms of magnesium. This is because magnesium has a charge of -1, versus oxygen's typical charge of +2. Two atoms of magnesium balances the compound. No, magnesium oxide would be MgO - the magnesium has an oxidation number (or charge) of +2, compared with -2 for oxygen, so one of each is needed to balance out the molecule. I don't think Mg2O exists.
