Answer:
Magnesium forms a positive ion and wants to lose electrons. Bromine forms a negative ion and wants to gain electrons.
Answer:
Magnesium forms a positive ion (Mg²+) and wants to lose two electrons.
Bromine forms a stable noble gas electronic
configuration when it gains one electron. Thus we find
magnesium as 2+ cation and bromine as a 1- anion in a
1:2 ratio in the compound .
Also, bromine forms a negative ion.
