Question

Why are metallic bonds non directional?

Answer 1

In chemistry, chemical bonds are three types of classification. This classification is based on electron binding in the bond. There are covalent bonds, ionic bonds and coordinate bonds. The covalent bond is nothing but the mutually sharing of electrons between the two atoms in the molecule. The ionic bond is nothing but highly electronegativity pulls the electrons towards itself, least electronegativity atoms lose the electrons in the molecule. The coordinate bond is nothing but the pair of the electrons from one atom to another atom in the molecule. It is mainly seen in coordination chemistry.

Complete answer:
In matters are divided into three types. There are solids, liquids and gas. Solids are divided into types. They are crystalline and amorphous. The crystalline is further divided into ionic solids, covalent solids, molecular solids and metallic solids.
The metal or metallic solids are made up of the metal bond. These metal bonds are hard in nature. It is one of the strong bonds and these bonds are used for the conductivity of electricity and thermal.
But are metallic bonds non directional because this bond is not like covalent bond, ionic bond and coordinate bonds. Metallic bond is nothing but the attraction force between the metal and electron cloud. So, this is completely non-directional.
According to the above discussion, we conclude metallic bonds are non-directional.

Note:
We represent the arrows by using the dipole-dipole interaction direction in the molecule. The electronegativity difference in the bonded atom plays a vital role whether the bond is ionic or covalent or polar covalent bond. The electronegativity difference between the bonded atoms is less than 1.7, which means it is considered a covalent bond. If the electronegativity difference between the bonded atoms is equal to 1.7, it is considered a polar covalent bond. If the electronegativity difference between the bonded atoms is greater than 1.7, it is considered a polar bond.
