The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Symptoms:** - The question describes a person with an impaired nervous system and signs of madness. This indicates a neurological issue possibly caused by a toxic substance. 2. **Identifying Potential Metals:** - The options provided are iron, calcium, lead, and fluoride. We need to analyze which of these metals is known to cause neurological problems. 3. **Analyzing Each Metal:** - **Iron:** While excessive iron can be harmful, it is not primarily known for causing madness or severe neurological impairment. - **Calcium:** Calcium is essential for nerve function, and its deficiency can lead to issues, but it is not typically associated with madness or severe neurological symptoms. - **Lead:** Lead is a heavy metal known to be a neurotoxin. It can cause severe neurological damage, cognitive impairment, and behavioral issues, including signs of madness. - **Fluoride:** Fluoride is primarily associated with dental health and is not known to cause neurological issues to the extent described. 4. **Conclusion:** - Based on the analysis, lead (Pb) is the metal that fits the description of causing an impaired nervous system and signs of madness due to continued intake through contaminated water. 5. **Final Answer:** - The metal responsible for the symptoms described in the question is **lead**. ---

On exposure to air, alkali metals get tranished due to formation of oxides, hydroxides and carbonates on their surface. When heated in air or oxygen they burn vigourously forming different types of oxides depending upon the nature of the metal. The formation and stability of these metals can be explained on the basis of size of alkali metal ion and the anion. Peroxides are colourless, while superoxides are coloured. The normal oxides are basic while peroxides and superoxides act as oxidising agents. Na_(2)O_(2) has light yellow colour. This is due to

A : Every metal has a definite work function , still all photoelectrons do not come out with the same energy it incident radiation is monochromatic . R : Work function is the minimum energy required for the electron in the highest level of conduction band to get out of the metal . Not all electrons in the metal belong to this level rather they occupy a continuous band of levels .

A metallic disc of radius r is made of a material of negligible resistance and can rotate about a conducting horizontal shaft. A smaller non conducting disc of radius a is fixed onto the same shaft and has a massless cord wrapped around it, which is attached to a small object of mass m as shown. Two ends of a resistor of resistance R are connected to the perimeter of the disc and to the shaft by sliding contacts. The system is then placed into a uniform horizontal magnetic field B and the mass m is released. Find the terminal angular velocity with which the disc will rotate finally. (Take r=10 cm , a=2cm , R=(1)/(100)Omega , B=0.2 T , m=50 gm , g=10m//s^(2) )

Solubility of an ionic compound in water is mainly dependent on: a.Lattice enthalpy , b. Hydration enthalpy Both these factors oppose each other and the resultant of these determines the solubility of an ionic compound in water. If lattice enthalpy has greater value, the compound is less soluble. In case hydration enthalpy has greater value, the compound is highly soluble in water. Compound of alkaline earth metals are less soluble than alkali metals, due to:

Alkali metals oxide are obtained by combustion of the metals.Although Na normally gives Na_2O_2 ,it will take up further oxygen at elevated pressure and temperature to form NaO_2 .The per and superoxides of the heavier alkalies can also be prepared by passing stoichiometric amounts of oxygen into their solution in liquid ammonia. The different alkali metal oxides can be distinguished by reaction with water.The superoxides reacts with CO_2 and give oxygen gas.The stability of per and superoxides is based upon that larger cation can stablise larger anion, due to larger lattice energy. Alkali metals dissolve in liquid ammonia.Dilute solutions are dark blue in colour but as the concentration increases above 3M, the colour changes to copper bronze and the solution acquires the metallic lusture due to the formation of metal ions clusters.The solutions of alkali metals in liquid ammonia are good conductors of electricity due to the presence of ammoniated cations and ammoniated electrons.However, the conductivity decreases as the concentrations increases, since ammoniated electrons and ammoniated cation associate. Solution of sodium metals in liquid ammonia is strongly reducing due to the presence of :
