IV. Chemical Bonding

IV. Chemical Bonding. Dots represent valence electrons. Everything else (inner shell electrons and nucleus) is called the Kernel and is represented by the symbol. Phosphorous has 5 valence electrons so we draw 5 dots around the symbol for phosphorous.

We now understand crystal structure and how to measure it

We now understand crystal structure and how to measure it. We now move into bigger condensed matter questions. First up: What holds a crystal together? (A hot topic in early CMP) Generalization to nonzero temps (Helmholtz free en(V,T)) gives eq . thermodynamics

Chemical Bonding

Chemical Bonding. Is an electrostatic force of attraction between atoms that holds them together. It is the exposed electrons in the outermost shell that are the ones most responsible for an atoms chemical properties, including its bonds with other atoms. Covalent Bond.
