Question
Which is the best description of metallic bonding?The electrostatic attraction between protons and electrons.The electrostatic attraction between a lattice of positive metal ions and delocalised electrons.The electrostatic attraction between positive nuclei and shared electron pairs.The electrostatic attraction between positive and negative ions.
Solution
The best description of metallic bonding is: The electrostatic attraction between a lattice of positive metal ions and delocalised electrons.
Here's why:
-
Metallic bonding is a type of chemical bonding that arises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions.
-
In a metal, the outer electrons of each atom are free to move about the entire metal, not just around the atom that donated them. This forms a 'sea' of delocalised electrons.
-
These delocalised electrons are attracted to the positive metal ions that make up the metal lattice structure, creating a strong bond.
-
This type of bonding gives metals their unique properties such as high electrical and thermal conductivity, malleability, ductility, and luster.
So, the statement "The electrostatic attraction between a lattice of positive metal ions and delocalised electrons" best describes metallic bonding.
