Non-directional bonds occur in metals as valence electrons are attracted to the nuclei of neighbouring atoms, however, this attraction is not in any particular direction giving birth to the phrase 'non-directional'. This is what gives metals there malleability or ability to be moulded into shape.
Directional bonds are the opposite, such as in an ionic substance where the positive ions are strongly attracted to negative ions forming a 3 dimensional lattice. This is why solids such as table salt is not malleable, it is an ionic compound with directional bonds.
Ionic bonds are often said to be non directional. This reflects the fact that the strength of electrostatic attraction is simply dependant on distance. Covalent bonds are directional as the electron pair sits between the bonded atoms
NO.Metallic bonds are non-directional bonds.
Metallic bonds are called non-directional because the electrons in a metallic bond are free to move throughout the entire structure rather than being localized between two specific atoms. This allows for the strong bonding between metal atoms in all directions, resulting in the characteristic properties of metals such as malleability and ductility.
Covalent bonds are 'electron sharing' bonds, as the name implies, but the sharing doesn't have to be equal. Any tendency for the shared electrons to favor one side of the bond over the other in their average distribution will lend an asymmetry to the arrangement of the atoms (if there are three or more atoms participating in the bond). A good example of a directional covalent bond is water, where the molecule has an angular structure due to the asymmetric distribution of electrons between hydrogen and oxygen.
yes ionic compounds are non rigid and non directional . Ionic bonds are non directional because the number of anions surrounded a cation is limited by the efficiency of its lattice packing therefore it is not directional afterall. However in covalent bonds, notice how the orbitals overlap, side-ways or head-on which defines the bond angle. The orbitals need to overlap in a specific direction in covalent bonding unlike in ionic bonding. As for rigidity it is the same concept as directional. Ionics bonds are non rigid because no matter how you rotate an anion around a cation, the bond is not affected, it is still the same. Whereas in covalent bonds, it is difficult to rotate the bonds especially in pi bond or side-ways overlapping due to the shape of p orbitals which results in rigidity, relatively
A non-directional hypothesis only proposes a relationship. In contrast, a directional hypothesis also proposes a direction in the relationship. For example, when one variable increases, the other will decrease.
Distance is nondirectional, such as ten feet, displacement is directional, such as ten feet east of my present position.
Covalent bonds of all types are directional in nature.

Ammonium chloride is a solid at room temperature because its molecules are held together by strong ionic bonds. These bonds keep the particles tightly packed in a crystalline structure, resulting in a solid state.
