Diamond, graphite and sand are continuous covalent substances.
No, quartz is not an ionic compound. Quartz is a mineral composed of silicon and oxygen atoms arranged in a continuous framework of SiO4 silicon-oxygen tetrahedra. It is a covalent compound rather than ionic.
Graphite is a covalent substance. It consists of carbon atoms linked together by covalent bonds in the form of layered sheets.

No, table sugar (sucrose) is a covalent compound, not an ionic substance. It is composed of carbon, hydrogen, and oxygen atoms held together by covalent bonds.
This is an insoluble or covalent compound.
Petrolatum is not one substance but a blend of different hydrocarbons, the structure of which will almost certainly be covalent.-- JT
Generally compounds formed between nonmetals are covalent.
A molecular formula represents a substance that contains covalent bonds. This formula shows the types and numbers of atoms present in a molecule, such as H2O for water, which consists of covalent bonds between hydrogen and oxygen atoms.
Generally compounds formed between nonmetals are covalent.
The giant structure involve an enormous number of atoms.
When a polar covalent bond and a nonpolar covalent substance combine, they may form a heterogeneous mixture where the polar and nonpolar components do not mix together. The polar and nonpolar substances will tend to separate due to their differing intermolecular forces.
they are weaker because the ions of substance have low electromagnetic which have covalent character to be low.
