Breaking the bonds of network structure is challenging because these connections often rely on established relationships and trust, making them resistant to change. Additionally, networks can create feedback loops that reinforce existing behaviors and norms, making it difficult for individuals or organizations to shift away from the status quo. Furthermore, the interconnectedness of members within a network means that altering one relationship can have cascading effects throughout the entire system, complicating efforts to make changes.
the diamond is very hard because it has crystallized at depth of 140-150 km( sometime it has crystallized at 300-400 km) into the earth to high pressure ranging approcimately betwen 45-60 kilobars and low temperature ranging approximately betwen 1652-2372 F(900-1300 C).AnswerIts hard because it consists of very small atoms (carbon) that are then tightly packed together and linked via covalent bonds (bonds where two atoms share an electron). It is the combination of very tight packing and very tight linking that results in diamond being so hard.
Salts typically form ionic solids, which are made up of positive and negative ions held together by ionic bonds. These solids have a crystal lattice structure and are typically hard and brittle.
Solids have a shape and a typical structure.

Carbon is one of the most versatile elements that is present in the universe. It is the dominating element in organic chemistry and it can bond with just about anything, even itself. Carbon usually forms covalent bonds with other elements, although it does form hydrogen bonds when it bonds with hydrogen
Carbon atoms can bond to other carbon atoms in a variety of ways, but when they bond in a network, with all the atoms bonding to all the other atoms that surround them, it is a very strong bond, stronger than the bonds formed in other minerals. Strong bonds are, by definition, hard to break. Hence the material is very hard. Scratching it requires breaking bonds.
Diamonds are hard because of their unique atomic structure, which consists of carbon atoms bonded in a strong, three-dimensional network. This network of bonds makes diamonds extremely resistant to scratching and breaking, giving them their renowned hardness.
Covalent bonds are hard to break because they involve the sharing of electrons between atoms, creating a strong bond. The electrons are held tightly between the atoms, resulting in a stable molecular structure. Breaking a covalent bond requires significant energy input to overcome the forces holding the shared electrons in place.
Covalent network solids are typically composed of nonmetal elements bonded together with strong covalent bonds in a continuous three-dimensional network structure. Examples include diamond (carbon), silicon dioxide (silica), and silicon carbide. These solids have high melting points, are non-conductive, and are very hard due to their strong covalent bonds.
This is because copper is held together by a sea of negative delocalised electrons which hold the positive copper ions in place. These bonds are very hard to break, meaning the metal has a high melting point...
Diamond is a structure known as a giant covalent network, formed from carbon. Each carbon is bonded to four others in a tetrahedral arrangement. Due to the atoms' size and the length of the bonds, this results in an extremely strong linkage, one which requires enormous amounts of energy to break or to deform. Because of this fact, diamond is both extremely hard (difficult, in fact nigh impossible to alter the shape of) and extremely difficult to break (not easy to destroy bonds).
Diamond is hard because of its strong and rigid molecular structure, which consists of carbon atoms bonded together in a repeating pattern. This structure makes diamond one of the hardest known natural materials, as the bonds between the carbon atoms are very difficult to break, resulting in its exceptional hardness.
Diamond is an example of a material that uses covalent bonds. In diamond, each carbon atom forms strong covalent bonds with four neighboring carbon atoms in a three-dimensional network structure. This results in a very hard and stable material.
Sometimes the bonds are strong. On the other hand, however, nitroglycerin is notorious for having breakable bonds. There is a class of compounds called "nonexistent". Their bonds break quickly.
Covalent crystals have strong covalent bonds between atoms, resulting in a hard and brittle structure. They have high melting and boiling points due to the strong bonds that hold the structure together. Covalent crystals are typically insulators and have low conductivity of heat and electricity.
Not very hard, depends on your bone structure. Some can be broken with a soft blow and some need to be hit very hard.
