Question

what is the vsepr geometry of the particle?

Explanation:

Step1: Determine the central atom

The central atom is \(N\).

Step2: Count the electron - pair groups

In \(NH_{4}^{+}\), \(N\) has 4 bonding pairs and 0 lone pairs. According to VSEPR theory, the electron - pair geometry and molecular geometry are the same when there are no lone pairs.

Answer:

tetrahedral
