For 10 points, identify this American chemist who developed an acid-base theory involving electron pair donors and acceptors and drew some dot structures to visualize the pairing of electrons in compounds.
In his work with non-ideal solutions of electrolytes, this man introduced a term which is given as molality times charge squared summed across all ions in a solution. Parameters representing electrostatic bonding and covalent bonding are utilized in an equation which gives the enthalpy change of a reaction involving substances named for him; that equation is the Drago-Wayland equation. He co-names a rule governing the contribution of components to the (*) fugacity of an ideal solution.  In his paper The Atom and the Molecule he introduced a notation in which non-bonding electrons are represented in pairs away from the lines indicating electrons shared between two atoms.
