Question
Draw the Lewis structure for (NH4+)
**Transcription for Educational Website: Understanding Lewis Structures for NH4⁺** The given task is to draw the Lewis structure for the ammonium ion (NH4⁺). Various representations are shown below, each labeled with a number from 1 to 7: 1. **Structure 1**: Nitrogen (N) is at the center, single-bonded to four Hydrogen (H) atoms. There are lone pairs of electrons shown around N, and the structure is enclosed in brackets with a plus (+) sign outside to indicate the positive charge of the ion. 2. **Structure 2**: Similar to Structure 1, but shown without lone pairs around the nitrogen. The setup shows N single-bonded to four H atoms, with brackets and a plus sign. 3. **Structure 3**: Exhibits a triple bond scenario, incorrectly depicting N with triple bonds to H atoms, which does not fit the correct valency or bonding scheme. 4. **Structure 4**: Displays N with three single bonds and one sticking out above N, suggesting incorrect bonding. Encased in brackets with a positive sign. 5. **Structure 5**: Another correct representation, identical to Structure 1, with N at the center bonded to four H atoms, enclosed in brackets with a plus sign indicating overall charge. 6. **Structure 6**: H4 bracketed with a central nitrogen atom, showing an incorrect negative charge inside and outside instead of the positive charge for NH4⁺. 7. **Structure 7**: Shows H4 with bracketed nitrogen and misplaced negative and positive indicators, which doesn’t accurately represent NH4⁺. **Explanation:** - **Correct Representation**: Structures 1 and 5 accurately depict the ammonium ion (NH4⁺) with nitrogen having four single bonds to hydrogen atoms. The presence of brackets and a "+" symbol illustrates its ionic nature. - **Incorrect Representations**: Structures 2, 3, 4, 6, and 7 show errors either in bonding style, electron configuration, or charge representation. The correct answer is Structure 1 or 5, accurately displaying the NH4⁺ ion’s Lewis structure.
