Covalent> Ionic> Metallic
Answers
Answer:
the correct option is 4. covalent>ionic>metallic
Order of bond strength is -
Covalent> Ionic> Metallic
Bonds involve exchange or sharing of electrons. These are the forces that join number of atoms to form molecules and compounds.
Covalent bond is the result of sharing of electrons. Nucleus of the involving atoms have equal effect on the electron and hence it is the strongest.
Ionic bonds is formed by mutual attraction of electrons. Here, one atom gains the electron while other loses.
Thus, one atom has greater share in electron over the other and hence easy to break.
Metallic bonds arise within metals where free electrons bind with cations of metals.
These delocalised electrons play important role in imparting property of conduction of heat and electricity.
