Question

Which among the following element reacts vigourously with $C{l}_2$.

• A. Magnesium
• B. Silicon
• C. Cobalt
• D. Arsenic

Answer 1

The correct option is A Magnesium

Chlorine is a non-metal, so it would react vigourously with highly reactive metals like sodium, potassium or magnesium.

Magnesium $Mg$ reacts with chlorine $C{l}_2$ to produce magnesium chloride $MgC{l}_2$.

$Mg+C{l}_2\to MgC{l}_2$
