    ANSWER
    Ammonia is present in small quantities in air and soil where it is formed by the decay of nitrogenous organic matter e.g., urea. On a large scale, ammonia is manufactured by Haber’s process. In accordance with Le Chatelier’s principle, high pressure would favour the formation of ammonia. Ammonia is a colourless gas with a pungent odour. Its freezing and boiling points are 198.4 and 239.7 K respectively. In the solid and liquid states, it is associated through hydrogen bonds as in the case of water and that accounts for its higher melting and boiling points than expected on the basis of its molecular mass. Ammonia gas is highly soluble in water. Its aqueous solution is weakly basic due to the formation of OH– ions. The presence of a lone pair of electrons on the nitrogen atom of the ammonia molecule makes it a Lewis base

    Werner's theory's important postulates are as follows: The central metal or metal atoms in coordination compounds have two forms of valency which are primary valency and secondary valency. The oxidation state corresponds to the primary valency, while the coordinate number corresponds to the secondary valency.

    As we move from left to right along a transition series, the nuclear change increases which tends to decrease the size but the addition of electrons in third-subshell increases the screening effect which counter balances the effect of increased nuclear charge.
