Element X' forms a chloride with the formula XCI₂, which is a solid with high melting point. X would most likely be in the same group of the periodic table as:
Si
Mg
Al
Na

Academic Chemistry NCERT Class 10

Correct Answer: (b) Mg

Explanation: Element Na form XCl halide. Mg forms XCl₂, Al forms XCl₃, and Si forms XCl₄halide. As an element, X forms a chloride with the formula XCl₂, hence the correct option is Magnesium.
