SiCl2Br2 would take a tetrahedral shape according to the VSEPR theory.
Ammonia and nitrogen are two distinct compounds, not a single compound that would have a molecular formula.

The Valence shell electron pair repulsion, or VSEPR is a simple technique for predicting the shape or geometry of atomic centers. The VSEPR formula is used in small molecules and molecular ions.
NaBr would be a formula unit as all sodium (Na) compounds are ionic.
SiCl2Br2 would take a tetrahedral shape according to the VSEPR theory.
According the VSEPR theory of molecular geometry, the geometry of SCl2 would be the same as H2O which is a bent angle
Ammonia and nitrogen are two distinct compounds, not a single compound that would have a molecular formula.
The shape of chloromethane is tetrahedral.
