How many electrons are transfered from a magnesium atom to each bromine atom in the formation of magnesium bromide?

Two electrons in total, are involved in the transfer,
but ONE is transferred to EACH bromine atom.
Looking at the formula:
MgBr2
As Mg is found in Group II,
it has 2 outer shell electrons.
Since according to the formula, there are 2 atoms of bromine bound to it, that means that EACH bromine atom has received ONE electron each, from the Mg2+ ion. In total, that would mean there was a transfer of TWO electrons.
Hope you're enlightened :)

Since bromine has 7 electrons in its outermost orbit, and magnesuim has 2, the 2 electrons from the magnesium atom get transferred to 2 bromine atoms.

magnesium has two electrons in its valence shell,so it donates its two electrons to bromium and thus magnesium bromide formed
