Answer: MBr2 is the resulting formula
Explanation:
Element M with Chlorine
M + CL2 --> MCL2
Element M with Bromine
M + Br2 --> MBr2
Chlorine and Bromine belong to the same group 7 known as HALOGENS. Both have an 7 outermost electrons, thus will react with Element M (most likely a metal in group 2) in the same way.
