In ______ bonding, the valence electrons are shared among all the atoms of the metallic elements.

Hint: For this problem, firstly we have to explain the type of bond in which only the sharing of the electrons will take place and not the complete transfer of the electrons to the atoms. Also, we know that only valence is responsible for making bonds.

Complete step by step solution:
- In the given question, we have to explain the type of bonding which is made when the hearing of the electrons between the metallic elements take place.
- As we know that there are so many different types of bonds which are found between nonmetals and metals such as a covalent bond, metallic bond, ionic bond, etc.
- But among all the bonds the sharing of the electrons take place only in the covalent bond.
- The covalent bond is found mainly between non-metals but in some metals such as transition metals, the presence of covalent is observed.
- As we know that the sharing of the valence electrons that are present in the outermost shell take place because they are loosely bound.
- Two types of bond are formed by the covalent bond that is sigma and pi bond.
- Sigma bond represents the single bond whereas double or triple bond represents the pi bond.
Therefore, a covalent bond is the only bond in which the sharing of the electrons takes place.

Note: In an ionic bond, the complete transfer of valence electrons takes place between the metal and non-metal. As we know that metals can donate electrons, so they donate valence electrons to the non-metals i.e. acceptor.
