Two(2).
They are ' Br^(2) ' . The terminal '2' indicates that there are two anions.
NB
Collectively they are IONS .
Positively charged ions are ' CATIONS'. M^(n+)
Negatively charged ions are ' ANIONS'. X^(n-)
MgBr2 =
Mg^(2+) ' positively charged cation
2Br^(-) ' negatively charged anions.
For an ionic compound to be neutral , the charged MUST balance and be opposite. (+/-)
Hence MgBr2 = 2+ for magnesium and "2 x -1 = -2 ' for the two bromines.
Hence + 2 - 2 = 0

What bond type is MgBr2?
MgBr2 (magnesium bromide) is an ionic compound. It is formed by the transfer of electrons from magnesium, a metal, to bromine, a non-metal, resulting in the formation of magnesium cations (Mg²⁺) and bromide anions (Br⁻). The strong electrostatic attraction between these oppositely charged ions constitutes the ionic bond in MgBr2.
How many elements are in mgbr2?
In 'mgbr2' there are NO elements. If you mean ' MgBr2'. Then the elements are ;- Magnesium (Mg) Bromine (Br) NB When writing chemical formulae, be it one or two letter symbol, the first letter is ALWAYS a CAPITAL letter. Hence my 'NO' for lower case letters. MgBr2 is magnesium bromide. It is a combination of one cation ( atom) of magnesium and two anions( atoms of bromine.
Which is the cation in mgbr2?
In the compound MgBr₂, the cation is magnesium (Mg²⁺). Magnesium donates two electrons to achieve a stable electron configuration, resulting in a positive charge. The anions in this compound are bromide ions (Br⁻), which balance the charge of the cation. Thus, MgBr₂ is composed of one magnesium cation and two bromide anions.
Formula for magnesium bromide?

How many anions are there in 2.50 g of MgBr2?
There are a total of 2 moles of anions in 2.50 g of MgBr2. Each formula unit of MgBr2 contains 2 moles of anions (Br-). The molar mass of MgBr2 is 184.113 g/mol, so 2.50 g is equivalent to 0.0136 moles, and therefore 0.0136 moles * 2 moles = 0.0272 moles of anions.
How many anions are there in 3.50 g of MgBr2?
There are 0.021 moles of MgBr2 in 3.50 g. Since MgBr2 contains 2 bromide ions per formula unit, there are 0.042 moles of Br- ions. So, there are 0.042 * 6.022 x 10^23 = 2.53 x 10^22 Br- ions in 3.50 g of MgBr2.

Magnesium and bromine elements combined?
When magnesium and bromine combine, they form magnesium bromide, a white crystalline solid. This compound is composed of magnesium cations (Mg^2+) and bromide anions (Br^-). Magnesium bromide is commonly used in various chemical processes and as a medication for certain conditions.
What is the ionic compound of MgBr2-6H2O?
The ionic compound MgBr2-6H2O is called magnesium bromide hexahydrate. It consists of one magnesium cation (Mg2+) and two bromide anions (Br-) per formula unit, along with six water molecules (H2O) bound to the compound.
What is the mass of 7 moles of MgBr2?
Using a copy of the Periodic Table, showing the Atomic Masses. MgBr2 1 x Mg = 1 x 24 = 24 2 x Br = 2 x 80 = 160 24 + 160 = 184 the Mr ( Relative Molecular Mass) of tne molecule of MgBr2 Using the equation. moles = mass(g) / Mr Then mass(g = moles X Mt So for '7' moles mass(g) = 7 x 184 = 1288 g = 1.288 kg ( kilograms).
