Tons are, but there is polar-covalent and nonpolar-covalent. Water, for example, is polar-covalent.
Polar means that the atom is not symetrical on an atomic level and could be linear, bent, or other shapes.
Non polar means it's symetrical, such as much tetrahedrals.

Water (H2O), sodium chloride (NaCl), and carbon dioxide (CO2) are examples of three compounds.
The three common compounds of neptunium are neptunium dioxide (NpO2), neptunium trichloride (NpCl3), and neptunium tetrafluoride (NpF4).
Carbon, Hydrogen and Oxygen are the three main elements of organic compounds.
Ionic compounds are bonded in a three-dimensional pattern called a crystal lattice. In this lattice structure, positive and negative ions align in a repeating pattern to achieve stability through electrostatic forces.
Some examples of covalent compounds with more than three elements include sulfur dioxide (SO2), phosphorus pentachloride (PCl5), and dinitrogen tetroxide (N2O4).
Compounds that contain carbon are called organic compounds. Carbon forms the basis of organic chemistry due to its ability to form diverse types of molecular structures.
