    The negative electron gain enthalpy of fluorine is less than that of chlorine. It is due to small size of fluorine atom. As a result, there are strong interelectronic repulsions in the relatively small 2p orbitals of fluorine and thus, the incoming electron does not experience much attraction.

    • The Solvay process is extensively used for industrial preparation of sodium carbonate (soda ash). The process is named after Ernest Solvay who developed the process during the 1860s.
    • Carbon dioxide reacts with the dissolved ammonia to form ammonium carbonate followed by ammonium hydrogen carbonate.

    2NH3 +H2O + CO2 ---> (NH4)2CO3

    (Ammonia)                 (Ammonium Carbonate)

    (NH4)2CO3 + H2O + CO2 --> NH4HCO3

    (Ammonium Carbonate)       (Ammonium hydrogen carbonate)

    NH4HCO3       +          NaCl  -->   NH4Cl     +    NaHCO3

    Sodium hydrogen carbonate crystal separates. These are heated to give sodium carbonate.

         2 NaHCO3       -->      Na2CO3 + CO2 + H2O

    But this process cannot be used to prepare potassium due to the high solubility of potassium bicarbonate and hence difficult to be precipitated by adding ammonium bicarbonate to a saturated solution of potassium

    An electrochemical cell is a device that can generate electrical energy from the chemical reactions occurring in it, or use the electrical energy supplied to it to facilitate chemical reactions in it. These devices are capable of converting chemical energy into electrical energy, or vice versa. A common example of an electrochemical cell is a standard 1.5-volt cell which is used to power many electrical appliances such as TV remotes and clocks.

    • The similarity in the properties of definite pairs of diagonally adjacent elements in the second and third periods of the periodic table is called diagonal relationship.
    • In s-block elements Lithium is the first element of group 1 whereas Beryllium is the first elementsof Group 2.
    • Some of their properties do not match with the properties exhibited by other elements of their group.
    • Instead their properties resemble the properties of the second element of the following group due to the similarity in ionic sizes and /orcharge/radius ratio of the elements.
    • Consequently lithium and magnesium have similar properties whereas Beryllium and Aluminium exhibit similar properties.

    In the elements of 4th, 5th and 6th period of the p-block the electrons present in the intervening d and f-orbitals do not shield the r-electrons of the valence shell effectively.
    As a result, {tex}{{ns}^{2}}{/tex} -electrons remain more tightly held by the nucleus and hence, do not participate in bonding. This is called inert pair effect.

    Elementary lithium is not very water soluble, but it does react with water. Lithium compounds such as lithium chloride, lithium carbonate, lithium phosphate, lithium fluoride and lithium hydroxide are more or less water soluble. Lithium hydroxide for example has a 129 g/L solubility.

    When an electron-releasing or an electron-withdrawing species is introduced to a chain of atoms (generally a carbon chain), the corresponding negative or positive charge is relayed through the carbon chain by the atoms belonging to it. This causes a permanent dipole to arise in the molecule and is referred to as the inductive effect.

    Alkali metal has one electron each in the valence subshell of their atoms. Since they have only one electron in valence subshell, therefore, they lose easily, owing to their low ionisation energies. Therefore, alkali metals are highly reactive chemically and do not exist in the free or native state.
