The valence shell of an atom in a legitimate Lewis structure (see Figure 2.3) has what in commonwith the valence shell of a noble gas? (Noble gases are stable elements found in the last column ofthe periodic table, e.g., He, Ne, Ar, etc.)
6.Examine the model and real structures for BF3. A.In what way does the central atom violate the octet rule? B.How many lone pairs are on each of the outer atoms in this molecule?
In the BEST Lewis structure for the molecule XeF2, how many non-bonding lone pairs (1 pair = 2) of electrons are found on the central atom?
In the BEST Lewis structure for the molecule XeF2, how many unshared pairs are there on the central atom? Enter a number.
This is a bit confusing for me but why aren't double bonds counted in the valence shell electron pair? For example, OPCl3 has 5 bonding pairs on the P atom (double bond with O and single bonds with Cl). Shouldn't the valence shell electron pair be 5 pairs not 4 pairs? So how come the VSEPR form is AX4??
Draw the Lewis Structure of XeF4 Molecular Geometry? Ideal Bond Angles? Are there Polar Bonds Present (Indicate on Lewis do structure Is there an Overall Dipole? Octet rule violator and how?
Consider a Lewis structure of acetamide H3C-C(O)-NH2 . a) How many shared and unshared electrons carbon atom attached to oxygen has in the above molecule? b) How many shared and unshared electrons hydrogen atom has in the above molecule?
How do you know when to draw a solid wedge vs a dashed wedge when drawing 3D bond-line structures? I know that solid-wedge means the atom is pointing towards you and dashed wedge means it's in the back, but how do you know which atoms are in the front as opposed to the back? How can you tell what the configuration will look like in space just by looking at the lewis structure or name?
How many total valence electrons are in N2?
Consider the SO 3 molecule. How many valence electrons does the molecule have? How many lone pairs of electrons are on the central atom? How many lone pairs of electrons in total are on the substituent atoms? How many resonance structures can be drawn for the molecule? If the ion doesn't exhibit resonance, indicate "1" as only one structure can be drawn for the molecule.
