Choose the correct word from the brackets to complete the following sentences. Anions are discharged at the anode during electrolysis. The tendency of the anions to get [reduced / oxidised ] at the anode increases on (ascending / descending] the electrochemical series.

Fill in the blanks with the appropriate word/s Increase in nuclear charge of an atom ________ [decreases/increases] the tendency of the atom to lose electrons.

Fill in the blanks from the choices given in the brackets: When ammonia [in excess] & chlorine are mixed, the chlorine is [oxidized to HCl, oxidised to N_2 , reduced to HCI]

in an ionic bond the cation tends to polarise the electron cloud of the anion by pulling electron density towards itself This causes development of covalent character in the ionic bond because the electron density gets localised in between the nuclei The tendency of the cation to bring about the polarisation of the anion is expressed as its polasising power The ability of ion to undergo polarisation is called its polarisability The polarising power of a cation or an anion is decided on the basis of F ajans' rules as follows . (i) The smaller the cation, the higher is its polarising power (ii) Cations with pseudo-noble gas configuration (ns^(2)np^(6)nd^(10)) have relatively high polarising power than those with noble gas configuration (ns^(2) np^(6)) (iii) The larger the size of the anion, the higher is its polarisability The ionic conductance of which of the following is the highest ? .
