Beryllium is very similar to-

Correct option is A

The correct answer is (a) Aluminium.
· Beryllium is chemically similar to Aluminium. Both elements share certain properties, such as high strength and low density. This similarity is due to their diagonal relationship on the periodic table, where elements in diagonal positions often exhibit similar characteristics.
· Beryllium and aluminium have similar chemical behavior, especially in terms of forming covalent bonds and showing resistance to corrosion.
Additional Information:
· Zinc: A transition metal with properties different from Beryllium.
· Radon: A noble gas, unrelated to Beryllium.
· Lithium: Although in the same period, it belongs to alkali metals and has different properties.
