There are 4 regions of electron density, 4 orbitals, around the central carbon atom; therefore.......

Explanation:

And therefore, the electronic geometry will be tetrahedral. Since all of these electron pairs represent #C-H# bonds, the molecular geometry will also be tetrahedral with #/_H-C-H=109.5^@#. Would the same geometry pertain to ammonium ion, #NH_4^+#? Why or why not?
