Please show full work when solving Molecular Structure and Physical Properties Consider the following statements and determine which are true and which are false. Silane (SiH4) is a non-polar molecule. Selenium tetrafluoride (SeF4) is a non-polar molecule. The formal oxidation state of an atom in a molecule (or molecular ion) can be calculated as: (the number of valence electrons on a free atom) minus (half the number of electrons in bonds to that atom) minus (the number of unshared electrons...
