Question

How many covalent bonds does nitrogen form if each of its unpaired electrons participate in one bond?

Answer 1

$\boxed{{\text{3}}\;{\text{covalent bonds}}}$ are formed by nitrogen if each of its unpaired electrons participates in one bond.

Further Explanation:

The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds are those compounds which are formed by the electron sharing between two or more non-metals.

The octet rule is the rule in accordance to which the elements have the tendency to bond with other elements and acquire eight electrons in their valence shells. This results in achieving a stable noble gas configuration.

For example, the formation of NaCl occurs according to the octet rule. The electronic configuration of sodium is   ${\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{1}}}$while that of chlorine is ${\text{1}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{s}}^{\text{2}}}{\text{2}}{{\text{p}}^{\text{6}}}{\text{3}}{{\text{s}}^{\text{2}}}{\text{3}}{{\text{p}}^{\text{5}}}$.

Chlorine is one electron short of the stable noble gas configuration and sodium can achieve stable configuration by losing an electron. So sodium loses an electron and forms cation and chlorine gains that electron to complete its octet.

The atomic number of nitrogen is 7. Its ground state electronic configuration is ${\mathbf{1}}{{\mathbf{s}}^{\mathbf{2}}}{\mathbf{2}}{{\mathbf{s}}^{\mathbf{2}}}{\mathbf{2}}{{\mathbf{p}}^{\mathbf{3}}}$ . The partial orbital diagram is the diagrammatic representation of the distribution of electrons in the valence shell only. In case of nitrogen, the valence shell is 2.

Nitrogen has five electrons in its valence shell. Out of these five electrons, two are paired while three remain unpaired. If all three unpaired electrons are to be used, it will accept three electrons from the neighboring atoms to make three covalent bonds.

Answer 2

Nitrogen could form 3 covalent bonds if each of its unpaired electrons participates in one bond.

Nitrogen atom forms 3 bonds based on octet rule, because it has 5 valence electrons. That means it needs 3 bonds or three more electrons.

Further Explanation;

Chemical bond  

• A bond is a type of force that is formed between atoms of different through the sharing or transfer of electrons.

Octet rule

• According to the octet rule for an atom to be stable it must have maximum number of electrons in its outermost energy level. Therefore an atom with four electrons requires four more electrons to attain stability.

Types of chemical bonds.

Covalent bond  

• This is a type of bond that is formed between non-metal atoms. It is formed as a result of sharing electrons between non-metal atoms involved.
• When atoms involved contribute equal number of electrons to the bond formation, the type of bond is known as covalent bond
• A covalent bond may be a dative covalent bond, when the shared electrons come from one atom.

Ionic bond  

• This is a type of bond that occurs between metal ions and non-metal ions. Ionic bond occurs as a result of transfer of electrons from one metal atom to another non-metal atom.
• After the transfer of electrons, metal atom loses electron to form a cation while the non-metal atom gains electrons to form an anion.

Other types of chemical bonds include;

• Hydrogen bonds
• Metallic bonds
• Dipole-dipole interactions, etc.
