Bonding Atoms to Form Molecules 1) Observe a) Atoms bond together to form molecules b) Some molecules are inorganic (non-living). c) Some molecules are organic (are/were living), containing all or part of Mr. Cohn. d) Atoms can bond ionically, whereby an atom gives up valence electrons and becomes a + ion, and another atom receives those electrons and becomes a – ion. The overall charge on the molecule then becomes zero. e) Atoms can bond covalently, whereby atoms share valence electrons, such that all atoms involved complete their valence rings (usually with a total of 2 or 8 electrons) f) Determining if atoms will bond ionically or covalently can often be done by noting their position on the periodic chart. Inorganic molecules can bond either ionically or covalently. Atoms closer to the ends tend to bond ionically, while those closer to the center, covalently. Organic or carbon-based molecules tend to bond covalently.
2) Problem Statement g) Can we build a model of the water (H20), Sodium Chloride/Salt (NaCI), and Methane (CH4) molecules? h) Can we determine the number of atoms per molecule via the model? i) Can we determine if each of the molecules is organic or inorganic, and if they bond ionically or covalently via the models? j) Can we determine if they are polar or non-polar via the models? k) Can we understand hydrogen bonding via the models
3) Hypothesis l) Using models made out of simple objects will help us better understand the structure of a molecule. Using color coordinated material will allow us to determine the number of atoms per molecule which will in turn help us understand if the molecule is bonding covalently, ionically, or is a hydrogen bond. This will help understand if the molecule is polar or non-polar or
