Statement-1: d-block metals have generally high M.P.
Statement-2: Greater number of electrons from `(n-1)d` in addition to ns electrons are involved in the interatomin metallic bonding.

Assertion (A): Transition metals have low melting points. Reason (R): The involvement of greater number of (n-1)d and ns electrons in the interatomic metallic bonding.

A 'd' block metal ion has magnetic moment of 1.7332 BM .The number of unpaired electrons are

Statement-I: Alkali metals are very soft metals Statement-II: Since the atoms of alkali metals have bigger kernels and smaller number of valence electrons, the metallic bonds in them are very weak and hence they are soft

Many transition elements also form 3+ ions by losing one (n-1)d electron in addition to the two ns electrons except

The sum of ns and (n-1)d electrons in Tc are

Elements with the general electronic configuration (n-1)d^(3)ns^(2) belong to which group in the modern periodic table ?

Statement -1 : Electrons move away from a low potential to high potential region. Statement- 2 : Because electrons have negative charge
