[" Q "11." Noble gases are group of elements "],[" which exhibit very "^(***)],[" O (a) High chemical activity "],[" O) Much paramagnetic properties "],[" (c) Minimum electronegativity "]

All the noble gases are colourless and tasteless monoatomic gases. In general, noble gases are least reactive and their inertness to chemical reactivity is attributed to the following reasons. Reactive and their inertness to chemical reactivity is attributed to the following reasons. (i)Except helium, all have completely filled ns^(2)np^(6) electronic configuration in their valence shells. (ii)All have high ionisation enthalpy and more positive electron gain enthalpy. However, a number of xenon compounds mainly with most electronegative elements like fluorine and oxygen have been synthesized under different conditions and fluorides of xenon have been used as an oxidising agent and a fluorinating agent in many of the chemical reactions Select the correct statement.

The elements of group 1 describe, more clearly then only 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 has the highest solubility in water ?

The group of radio active element which can decay to give two noble gases is __________

Observe the following statements. Q I. The physical and chemical properties of elements are periodic functions of their electronic confirguration. Q II. Electronegativity of fluorine is less than the electronegativity of chlorine. Q III. Electropositive nature decreases from top to bottom in a group. The correct answer is
