$sube$ Suppose a student repeats Experiment $1$ using an unknown metal instead of magnesium. The unknown metal reacts similarly to magnesium. The student adds $4\mathrm{.}67g$ of the unknown metal to a crucible that has a mass of $35\mathrm{.}00g.$ The crucible and its contents are heated over a Bunsen burner for several minutes. The mass of the crucible and its contents after heating is $40\mathrm{.}85g.$

Identify the unknown metal based on the results of the experiment. Assume all of the unknown metal reacts.

$Sr$

$Ni$

$Zn$

$Ca$

$Cu$
