8A transition metal ion has one electron removed from the 5s orbital. Giving it a completely empty 5s shell and a completely filled 4d orbital. What is the ion?

Based on what you know about electron configurations explain why Sb would form +3 and 5+ ions? Write out their electron configurations. 3 with? How many total electrons can you have with the quantum number Lewis Structures and VSEPR Model Lewis Structures The electrons involved in bonding are the valence shell electrons Number of electrons in the valence shell is determine by row # excluding the transition metals Count the number of electron each atom brings in…..That is the total number of electrons you are allowed to have in the molecule. Put the least electronegative element in the middle of the structure Nature likes symmetry Terminal atoms (atoms at the end of the Lewis structure) always satisfy the octet rule Fluorine and Hydrogen (Hydrogen can only have 2 electrons) always only make one bond N, O, and F always obey the octet rule Atom in the second row of the periodic table cannot have more than 8 electrons surrounding it because no d prbitals are close enough in energy to use Formal charge 1. Sum of all the formal charges is equal to the overall charge on the molecule

2. Minimize the number of atoms with a formal charge 3. Minimize the magnitude of the formal charge (we don’t like #’s >1) 4. A more electronegative element is more likely to have a negative formal charge (there are exceptions) Problems Draw the Lewis structures of the following compounds SF 4 NO 2 NO 3 - IO 3 - PO 4 3- Draw 3 possible Lewis structures for COS. Assign Formal charges. Which structure is the best and why? VSEPR Model Basic Geometry 0 lone pair (shape) 1 lone pair (shape) 2 lone pair (shape) 3 lone pairs (shape) Hybridizatio n
