Now by rearranging this equation to solve for the molecular weight we obtain the equation of MW= mRT/VP = dv ⋅ RT/P.

Chemical bonds form different shapes based on the arrangement of their atoms. To determine the shape of the molecule, the number of shared and lone pairs of electrons must be determined. To do this, you must count the available bonding electrons each atom has. Then you must determine central atoms and terminal atoms. A planetary model of a nitrogen atom could look something like this: In the planetary model, a nitrogen atom has a central nucleus, composed of seven protons and seven neutrons, surrounded by seven electrons. The Bohr Model. Scientists soon realized that the planetary model was an inaccurate description of atomic structure.

In many simple compounds, valence bond theory, the Valence Shell Electron Pair Repulsion model , and the concept of oxidation number can be used to explain molecular structure and composition. An ionic bond is formed when a metal loses one or more of its electrons, becoming a positively charged cation, and the electrons are then gained by the non-metal atom, becoming a negatively charged anion.
