Solution

The correct option is C Magnesium
The alkali metals are a group (column) 1 in the periodic table consisting of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
Hence, magnesium is not an alkali metal.

Q. A metal forms strong base and stable carbonates.
The metal belongs to:
Q. Comprehension:
The elements of group 1 describe, more clearly than any other group of elements, the effects of increasing the size of atoms or ions on the physical and chemical properties. The chemical and physical properties of the elements are closely related to their electronic structures and sizes. These metals are highly electropositive and thus form very strong bases, and have quite stable oxo-salts. In the manufacturing of sodium hydroxide, chlorine and sodium carbonate, the sodium chloride is used as starting material.

Which of the following acts as an oxidising as well as reducing agent ?
