Ammonium Ion (NH₄⁺) Molecular Structure - 3D Ball-and-Stick Model #3855377 (License: Personal Use)

This image displays a ball-and-stick molecular model of the ammonium ion (NH₄⁺), where the central pink sphere represents a nitrogen atom and the four surrounding white spheres represent hydrogen atoms. The bonds are shown as cylindrical connectors, illustrating the sp³ hybridization and perfect tetrahedral symmetry (≈109.5° bond angles) characteristic of this polyatomic cation. The model emphasizes spatial geometry critical for understanding acid-base chemistry and ionic behavior in solutions.

Used in educational chemistry resources, textbooks, and online learning platforms to teach molecular geometry, VSEPR theory, and ion structure; matches user intent for visualizing NH₄⁺ for homework, lectures, or self-study.
