The shape of the ammonium ion, NH4+, is tetrahedral.

Here's why:

1. First, we need to understand the structure of the ammonium ion. It consists of one nitrogen atom (N) and four hydrogen atoms (H). The nitrogen atom is at the center, and the four hydrogen atoms are surrounding it.

2. The nitrogen atom forms four bonds, one with each hydrogen atom. These bonds are arranged in such a way that they are as far apart from each other as possible. This is due to the fact that electrons in bonds repel each other.

3. The arrangement that allows the four bonds to be as far apart from each other as possible is a three-dimensional shape known as a tetrahedron.

4. Therefore, the shape of the ammonium ion, NH4+, is tetrahedral.
