Which of the alkali metals has the polarizing power close to that of Magnesium ?
A polariser in used to
A polariser in used to
Assertion Among two cations of similar size the polarising power of cation with pseudo noble gas configuration is larger than cation with noble gas configuration Reasoning Polarising power of Ag^(o+) is more than K^(o+) .
Which has maximum polarising power in cation ?
The diagonal similarities are due to similar polarising powers for the elements. The polarising power is defined as
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 Arranfe of the following species in dereasing order of polarising powers Ag^(o+),TI^(o+),Na^(o+) .
