Solve this multiple-choice question and choose the correct option.

Given data Nitrogen: Z = 7, valence shell 2s22p3. Concept/ApproachIn neutral covalent compounds (e.g., NH3) nitrogen forms three covalent bonds; however, its maximum covalency is four, as in NH4+, where N forms three normal covalent bonds and one dative (coordinate) covalent bond, totaling four covalent bonds. NoteAs a second-period element (no d-orbitals), nitrogen's maximum covalency is limited to 4. Final Answer4

Chemical bonding (valency): What is the maximum number of covalent bonds nitrogen can form? Consider valence-shell capacity for nitrogen (period 2) and typical compounds like ammonium. Choose the correct option.

Difficulty: Easy

Correct Answer: 4

Explanation:

Given data

Nitrogen: Z = 7, valence shell 2s²2p³.

Concept/ApproachIn neutral covalent compounds (e.g., NH₃) nitrogen forms three covalent bonds; however, its maximum covalency is four, as in NH₄⁺, where N forms three normal covalent bonds and one dative (coordinate) covalent bond, totaling four covalent bonds.

NoteAs a second-period element (no d-orbitals), nitrogen's maximum covalency is limited to 4.

Final Answer4
