Question

How do metallic bonds differ from covalent bonds?

Answer 1

Hint: The metallic bond and the covalent bonds are the two types of chemical bond where the attractive forces hold the atoms together which forms a chemical compound. The example of covalent compounds is water and the example of metallic bond is metallic bonding in sodium.

Complete step by step answer:
The attractive force which holds the atoms or the group of atoms together in a chemical compound is known as a chemical bond. The chemical bonds are of various types. The two chemical bonds which are asked are explained below.
The covalent bond is the chemical bond formed by the sharing of electrons between the two atoms. The covalent bond is observed between two nonmetals.
Metallic bonds are the chemical bonds that are formed between the two metal atoms.
The difference between the metallic bonds and the covalent bond is shown below.

Covalent bond	Metallic bond
In covalent bonds valence electrons are shared by two atoms.	In metallic bond attraction is observed between the two metal cations and delocalized electrons.
The binding energy in covalent bonds is higher than the metallic bond.	The binding energy in metallic bonds is lower than the covalent bond.
The covalent bond has very low conductivity.	The metallic bond has high conductivity.
Covalent bond is directional bond.	Metallic bond is a non-directional bond.
It is present in all three states: Solid, liquid and gas.	It is present only in one state: Solid
Covalent bond is unmoldable	It can be molded.
It has a lower melting point.	It has a higher melting point.
It is non-ductile	It is ductile
It has lower boiling point.	It has higher boiling point.

Note: You must know that the charge held by the metal cation affects the strength of the metallic bond the greater the magnitude of the charge, the stronger will be the force of attraction between the electron sea and the cations.
