Types of Chemical Bonds and Definitions

To determine the types of chemical bonds for the given substances and provide definitions for covalent bonds, let's fill in the table:

| № | Type of Bond | Definition and Formulas | |---|--------------|------------------------| | 1 | Covalent Bond | Definition: A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms. It occurs between nonmetal atoms. Covalent bonds are characterized by the sharing of electrons to achieve a stable electron configuration. | | | | Formulas: N2, N2O5, O2, HNO3, SO2, CI2, O3 | | | | | | 2 | Ionic Bond | Definition: An ionic bond is a chemical bond formed by the transfer of electrons from one atom to another. It occurs between a metal and a nonmetal. Ionic bonds are characterized by the electrostatic attraction between positively and negatively charged ions. | | | | Formulas: Na2O, CaSO4 | | | | | | 3 | Polar Covalent Bond | Definition: A polar covalent bond is a type of covalent bond where the electrons are not shared equally between the atoms. It occurs between atoms with different electronegativities. Polar covalent bonds are characterized by a partial positive charge on one atom and a partial negative charge on the other. | | | | Formulas: HCl |

Let's now discuss each substance and determine the type of chemical bond for each.

1. N2: Nitrogen gas (N2) consists of two nitrogen atoms bonded together by a triple covalent bond. The atoms share three pairs of electrons, forming a stable molecule. [[1]] 2. N2O5: Dinitrogen pentoxide (N2O5) is a covalent compound. It consists of two nitrogen atoms and five oxygen atoms bonded together by covalent bonds. The bonds between the nitrogen and oxygen atoms are covalent, involving the sharing of electrons. [[2]] 3. HCl: Hydrogen chloride (HCl) is a compound formed by the reaction of hydrogen and chlorine. It is an example of a polar covalent bond. The chlorine atom is more electronegative than the hydrogen atom, resulting in an unequal sharing of electrons and a partial positive charge on the hydrogen atom and a partial negative charge on the chlorine atom. [[3]] 4. O2: Oxygen gas (O2) consists of two oxygen atoms bonded together by a double covalent bond. The atoms share two pairs of electrons, forming a stable molecule. [[4]] 5. CaSO4: Calcium sulfate (CaSO4) is an ionic compound. It consists of calcium ions (Ca2+) and sulfate ions (SO42-) held together by ionic bonds. The calcium atom donates two electrons to the sulfate ion, resulting in the formation of an ionic bond. [[5]] 6. HNO3: Nitric acid (HNO3) is a covalent compound. It consists of a hydrogen atom, a nitrogen atom, and three oxygen atoms bonded together by covalent bonds. The bonds between the atoms are covalent, involving the sharing of electrons. [[6]] 7. SO2: Sulfur dioxide (SO2) is a covalent compound. It consists of a sulfur atom and two oxygen atoms bonded together by covalent bonds. The bonds between the atoms are covalent, involving the sharing of electrons. [[7]] 8. Cl2: Chlorine gas (Cl2) consists of two chlorine atoms bonded together by a single covalent bond. The atoms share one pair of electrons, forming a stable molecule. [[8]] 9. O3: Ozone (O3) is a covalent compound. It consists of three oxygen atoms bonded together by covalent bonds. The bonds between the atoms are covalent, involving the sharing of electrons. [[9]] 10. Na2O: Sodium oxide (Na2O) is an ionic compound. It consists of sodium ions (Na+) and oxide ions (O2-) held together by ionic bonds. The sodium atom donates one electron to the oxide ion, resulting in the formation of an ionic bond. [[10]]
