ABOUT COCARD. Since 1999, COCARD has been a company composed of like-minded, owner-operated, sub-ISOs. We have formed an entity whose purposes and structure allow us to capitalize on collective bargaining benefits and a mutually leveraged exit strategy.

Description of his model: Bohrâs atom like Rutherfordâs contained a dense, positive nucleus. He expanded on Rutherfordâs ideas, turning his attention to describing the electron. He stated they moved in fixed, circular orbits (or energy levels) around the nucleus, these called electron shells.
When compiled, data from Schrodinger's equations can be used to create an electron probability diagram or the electron cloud for a specific atom. The electron cloud model was created as a compromise between what physicists did understand about electron behavior and what they didn't understand.
