An element (A) belonging to group number 1 and period number 3 react with dihydrogen to form an hydride (B). The element (A) reacts with the universal solvent to give a strong base (C). Identify A, Band C.

An alkali metal (A) belongs to period number II and group number I react with oxygen to form (B). (A) reacts with water to form (C) with liberation of hydrogen compound Identify A, B, C.

An element occupies group number 1 and period number 3. This element when exposed to air gives compound (A). The element with water forms compound (B). Which is a strong base und (A) with ammonia gives compound (C ) which is used as reducing agent in organic chemistry. The element reacts with an halogen and forms cooking salt (D). Identify A, B, C and D.

An element 'A' occupies group number 15 and period number 3. It reacts with chlorine to give B which further reacts with chlorine to give C at 273 K . Both B and C are chlorinating agents for organic compounds. C is a better chlorinating agent because it chlorinates metals also. B reacts with SO_(3) and reduces it to SO_(2) . B has a pyramidal shape. C has trigonal bipyramidal shape by sp^(3)d hybridisation. Identify the element A and the compounds B and C. Write the reactions.

An element belongs to group 1 and period 3 reacts with chlorine gas to form A. (A) reacts with ammonium bicarbonate to give compounds (B) and (C). Compound period is beryllium (A). (B) is then heated to give compound (D). Identify A, B, C and D and write the respective equations.
