Question

The element M forms a stable ionic compound MCl 2. If M were allowed to react with bromine, the resulting compound would have the formula:________.

Answer 1

Answer: MBr2 is the resulting formula

Step-by-step 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.
