Question

In models of molecules, gray spheres are carbon atoms, white sphere are hydrogen atoms, red sphere are oxygen atoms, and blue sphere are nitrogen atoms.

which model represents a molecule of ammonia, NH 3?

Answer 1

Answer:

A molecular model, in this article, is a physical model that represents molecules and their processes. The creation of mathematical models of molecular properties and behaviour is molecular modelling, and their graphical depiction is molecular graphics, but these topics are closely linked and each uses techniques from the others. In this article, "molecular model" will primarily refer to systems containing more than one atom and where nuclear structure is neglected. The electronic structure is often also omitted or represented in a highly sophisticated way .

NH3 Ammonia

Ammonia has 4 regions of electron density around the central nitrogen atom (3 bonds and one lone pair). These are arranged in a tetrahedral shape. The resulting molecular shape is trigonal pyramidal with H-N-H angles of 106.7°.
