Answer:
The charge of the metal is +5.
Step-by-step explanation:
As the chlorine atom has a valence of -1, and the metals have a positive valence, we have to look for the charge that makes the molecule neutral.
In this case, there are 5 Cl, so the total negative charge of Cl is -5.
To make the molecule neutral, the metal must have a positive charge of +5.
