What is the shape of NH4?
Understand the Problem
The question is asking about the geometric structure or shape of the ammonium ion (NH4+). To determine the shape, we consider factors such as the number of bonds and lone pairs around the nitrogen atom.
Answer
Tetrahedral
The shape of NH4+ is tetrahedral.
Answer for screen readers
The shape of NH4+ is tetrahedral.
More Information
The NH4+ ion (ammonium ion) has a tetrahedral shape due to its sp3 hybridization, with bond angles of 109.5 degrees. The central nitrogen atom forms four equivalent bonds with hydrogen atoms, creating a symmetrical geometry.
Tips
A common mistake is confusing the geometry of NH3 (pyramidal) with NH4+ (tetrahedral). NH4+ lacks a lone pair on the nitrogen, leading to a symmetrical tetrahedral shape.
