C. Sometimes sulfur is in the center; sometimes fluorine is in the center. … A. The central atom is fluroine. How to draw the Lewis Structure of SO2 - with explanationCheck me out: B. 2. The arsenic atom is surrounded by 4 regions of electron density, which means that its has a steric number equal to 4. If you are having trouble with Chemistry, Organic, Physics, Calculus, or Statistics, we got your back! Coordination number: 5: Bond angle(s) 90°, 120° μ (Polarity) 0: In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid. In the Lewis structure for SF2, which of the following is true? What word describes the molecular shape of CBr4? 1. Our videos prepare you to succeed in your college classes. The steric number (which determines what geometry/shape the molecule takes) is equal to this number divided by two, so the steric number here is 4 - which corresponds to a tetrahedral geometry. A quick explanation of the molecular geometry of PF3 including a description of the PF3 bond angles. Our videos will help you understand concepts, solve your homework, and do great on your exams. A. Let us help you simplify your studying. This means that the central atom can bond to a possible FOUR other atoms - but here, it is only bonded to TWO, meaning that there are (4-2)=2 lone pairs of electrons. Each of the chlorine atoms will have 3 lone pairs, which will bring the number of valence electrons used to 24 The remaining two valence electrons will be place on the arsenic atom as a lone pair. The central atom is sulfur.
