This is called a Network solid.
Network Solids are atomic solids that contain strong directional covalent bonds to form a solid that might be best viewed as a giant molecule.
Diamond has an octahedral structure.
Ionic bonds create stronger intermolecular attraction than covalent bonds do; that is why rocks are harder than plastic.
no. melting is a physical change and does not involve breaking of covalent bonds

covalent bonds
covalent bonds join all the atoms tightly together

no
Diamond has an octahedral structure.
Breaking covalent bonds throughout the solid would be required to melt a network solid.

Sand (SiO2) is a network covalent solid. It's considered to be extremely strong with relatively high melting points (>1550'C). It is made by atoms making multiple bonds with other atoms in the "network". To compare, another example of a network covalent solid is diamonds.
quite simply, bonds. The strength of these bonds depends on the type of element or compound that forms the solid. These 'particles' you refer to are best known as 'atoms' and the atoms that form a solid are held together by these bonds.
they look like three spheres.a big one in the middle and two smaller ones on the ends
