In metallic bonding, the ‘sea of electrons’ that are accumulated from all the metal atoms act as a ‘glue’ between all the metal ions holding them together very strongly. What constitutes this ‘sea of electrons’?

Solution

The correct option is C Valence electrons
In a metallic substance, all the metal atoms are bound together with the force of attraction between valence electrons and the metal ions.

The ‘valence electrons’ from every metal atom form a sea of electrons which are shared between many positive ions. The sea of electrons act as a "glue" giving the substance much strength.

Q. Assertion :Group 2 metals have higher melting points when compared to the group 1 metals. Reason: +2 charge on the cations in the metallic lattice causes them to be more strongly attracted to the sea of electrons and making it difficult to pull them apart.
